XPS 8930, what does EP_EXCEPTION SUB_HEADER mean?

Hi,

After installing a few new updates on my 8930 PC,  without warning or my trying to execute anything, my monitor turns to black and I get the message, in white letters, "EP_EXCEPTION SUB_HEADER" with a button underneath with "EP_EXCEPTION" displayed.   Not knowing what to do, I clicked on the button and the black and white screen went away and it turned all blue (the Dell color blue)  On the Task Bar line was a "Dell" circle that said "My Dell".  When I hit escape, it goes away.  It doesn't seem to affect anything, other than being annoying.

I don't remember after which update I installed that this started happening.

I don't like this and need help on how to remove it.

Thanks.

Jerry

@jmallard   - System Restore shouldn't be taking hours.  I've had occasions where a Restore on my XPS 8930 also wouldn't finish.  In those cases, I force powered off, crossed my fingers, and rebooted.  At least for me, a message appeared up saying "Restore incomplete, system not changed". So everything was was before starting the Restore. YRMV...

I also thought of that Realtek audio problem for your boot delays. But unless this has been going on for a rather long time, that may not be the issue.  Dell removed the problem Realtek audio driver v6.0.9025 more than a year ago and reposted v6.0.8248 from 2019 which is good.  Realtek audio driver v6.0.9107.1 is newer that .8248 and good too, but -for whatever reason- Dell didn't repost this one.  I'm running 9107.1 on my XPS 8930 and boot times are ~12 sec.  Check which version Realtek audio driver is installed on your PC when you get safely back to your desktop.

And one more thingy...You don't want/need to make any changes in BIOS setup to change boot order.  Just plug a bootable USB into PC with power fully off, or insert bootable DVD into the drive and power PC fully off.  Then power on and tap F12 to open the boot menu. Select option to boot from USB (or from DVD) and PC will boot.

Ron,

I did not get to bed until after 3am this morning.  PC was still running System Restore.  I just went ahead and went to bed and let the PC running.  Figured it would either work or crash.

Didn't get to it until early this afternoon and it was sitting there with the blue welcome screen displaying date and time. 

Got an error message that "Restore incomplete, system not changed".  Of course, that didn't fix the boot problem.

I checked Device Manager and found this was my installed driver for Realtek:

Realtek Driver 6.0.9205.1 dated 7-13-2021.jpg

Appears that I have had the slow boot for a lot longer that I remembered.  At my age, time really goes by fast.

So, I rolled back that driver to the previous driver and I was presented with this:

Realtek Driver 6.0.9107.1 dated 1-19-2021 (current).jpg

That really made me feel good after all this searching and reading.  So I shut down and rebooted and my start up time went from 1:40 seconds to ~30 seconds.  Sadly, not 10 the second area like you and others are reporting, but it is a lot better than ~1:40 seconds.

Just wondering, I did notice in Device Manager/Audio inputs and outputs/Speakers / Headphones (Realtek Audio)/Properties/Driver:

Realtek Driver (Speakers) 10.0.19041.1.jpg

This driver hasn't posed any problems for anyone that you know of - has it?

Well, I need to mark this one "Solved" but I'm not sure where.  Found a cure for 3 of my problems:

1. EP_EXCEPTIOIN SUB-HEADER random display.  Fixed by removing all "Killer" and "Dell" applications.
2. Not able to access the boot menu.  PC never displayed a "Dell" logo at startup.  Fixed by moving one of the monitor HDMI cables to the Graphics Card HDMI on-board plug in.
3. Slow boot up time improved from 1 minute 40 seconds to ~30 seconds.  Roll back of Realtek to previous version.

Thanks again for al your detailed help and to the others that contributed much information that I didn't know.

This Forum is a GREAT PLACE !!

ProfessorW00d,

Thanks for your prompt response, I didn't expect it so soon.

From reading the posts suggested by your link I assume the problem has something to do with the Killer Intelligence Center.  I just noticed this is installed on my computer and I never opened it until today.  I am not a game player and do not have any Alienware or any other aftermarket game software installed.

I could not find anywhere to stop GameFast in the application since I don't know the first thing about it.

I noticed that I did install "Killer PCIe Ethernet Controller Driver" and "Killer Control Center Application" from the "recommended' list on Dell Support for updates.

I found that "Killer Ethernet Performance Driver Suite UWD" is installed in my Programs and Features listing.

Should I delete this from my computer ?  I will never use it anyway.  I guess I won't be installing "recommended" software without investigation in the future.

Thanks for your help.

Jerry

@jmallard  - Click Start>Run and type in: services.msc and click OK.

When services.msc opens, double-click each Killer entry and set its Startup type to Disabled. Then do the same for all xTend services that are listed. Don't change anything else in services.msc. Just close services.msc.

Next, open Task Manager and click Startup tab. If any Killer entries (eg, Killer Intelligence Center) is listed there, right-click and disable them.  Then just reboot the PC.

You don't need any of that Killer junk and IMO, Killer Ethernet works better on my XPS 8930 without any of that stuff running in the background.

Agreed. Same with my Aurora-R6.

Actually, in my Windows-11 Reliability History report, I even observed it quietly crashing (bring down my perfect score).

I just uninstalled it from "Programs and Features". I do not see any lingering Services (so, at least it appears to uninstall properly).

Thanks for your response.

I disabled all of the Killer titles in my Services.

However, after a shutdown and restart, I still get the unwanted random display.  I don't know what triggers the display.

I appreciate you taking time to make a suggestion for my problem.

Since that didn't work, what you describe above seems (to me) to point to Support-Assist and/or Dell-Update.

You could try uninstalling both and rebooting. I don't use either on most Dell systems (ie, first sign of trouble, I uninstalled them). And when clean-installing Windows to a Dell, I never re-install them (or really, anything developed and distributed by Dell) ... there is just no reason to.

@jmallard  Try doing a Windows System Restore to the last restore point available before the problems started.

Be good idea to image your boot drive and save the image on an external USB drive before doing the restore, to be safe. Macrium Reflect (free) would be a good tool to create the image, if you don't already have an imaging app.

Be sure to include all partitions Macrium identifies on the boot drive, and select the option to validate the image as soon as it's created, which you have to select on the Advanced options screen before you create the image

Tesla 856 and RoHe,

Thanks for your responses.  

I need a few minutes to craft a response to your posts.  I can get into more details that is necessary to explain a problem sometimes and I want to avoid that.

Thanks.

Tesla 856 and RoHe,

I'm an old guy (78), set in my ways, but I am patient.

My Dell 8930 is 2.5 years old.  I only have it because my old Dell XPS 720 would not run Windows10 properly.  My last 3 computers were purchased only because Microsoft stopped supporting older versions of Windows.

I noticed that my computer seem to be slower that it used to and it takes a long time to boot up (1 1/2 minutes). 

I did experience problems with Dell Support Assist.  Uninstalled and now it won't re-install and I see that a lot of people don't use it.  I have good current backup, I use Acronis True Image software.

I hate the thought of having to re-install everything on my computer and haven't done so since I got this computer.  But I'm pretty sure that is the only way to solve my problems.

I keep all my data, photos, etc. stored on a separate physical drive (a 1TB SSD Drive E: ).

I need to know which option I need to choose for a re-install of Windows 10:
  - Keep my files
  - Remove everything

I believe this computer has the restore partitions to re-install Windows to the state I received it from Dell.  I don't have a physical DVD or anything with Windows 10.

Going to try and include a copy of my disks/partitions.

Thanks for your help.
