Thunderbolt Firmware update locks laptop
My Latitude 5401 went to update the Thunderbolt 3 Firmware and it locked the laptop up. Had to do a hard shutdown.
Laptop on reboot did a disk repair on C: and then on reboot I noticed that my thunderbolt dock is no longer connecting.
I tried running the firmware update manually by downloading it from DELL website and that locked up laptop right away. Tried the previous version and same result.
Maybe some kind person could provide some steps to diagnose and repair this.

I am seeing this same issue on Windows 10 v1903 with the latest patches installed. Tested on my 7540 and two 7400s. Also running the TB16 dock firmware updater causes the same issue.

I have the same problem too, and I'd sure love to have a fix for it.

I have seen this on 3 Latitude 5501 laptops so far, with Windows 10 v1909. As soon as the update launches the system freezes, not able to use mouse or Ctrl+Alt+Del. The fans rev up but nothing happens. Have had to hold the power button down to shut the system off. The drivers section on the Dell support site say this is an Urgent update. I have tried different user profiles, domain and local, and tried Run as administrator, all lock the system up.

Same experience.
would conclude this is a DELL/Microsoft issue and the best thing to do is avoid this patch at all costs.
@Anonymous get this fixed!
btw I got my thunderbolt working with a board swap.

Seen on Latitude 7400 (4.44.118.001)
XPS 13 (4.44.106.031) does not have the issue (that I have seen)

Try disabling SMM Security Mitigration in the BIOS under Security. Then run the firmware update in the OS.

@WillKT That seems to have resolved the issue. It would be nice if Dell could find out what changed recently to cause this issue.

this worked on a Latitude 7400 (laptop, but there is a thread for the 2-in-1 which seems to say it works there too)

The latest Thunderbolt Firmware 4.44119 and Driver 1.41 worked for me and for turning off SMM also works.

I was skeptical about this but it did the trick on my 7400. Thanks @WillKT !
