poweredge 2650, smp linux boot hangs
my pe2650 hangs pretty consistently during the boot sequence.
The problem is quite repeatable via several mechanisms.
note: booting non-smp kernels seems to work reliably.
--test 1
-install fedora core 1
-boots ok and seems to run reliably
-install all updates
-at some point during bootup, system hangs, screen goes black, keyboard leds don't respond,
and the system doesn't respond to the network
--test 2
-install "minimal" fc1 and no updates
-hangs after "Finding module dependencies"
--test 3
-install minimal fc2b
-hangs after "Finding module dependencies"
(I find this very strange... fc2b should be a pretty different beast with the 2.6 kernel)
-boot the non-smp kernel and disable everything non-essential (especially apm, acpi, ....)
-smp kernel now seems to boot reliably
I have another pe2650 which hasn't had a problem with fc1, but I think it's bios
is older, so I'm going to try bumping the bios down (from a17 to a16).
anyone else run into this or have any ideas?

I have exactly this problem. I am resorting to Fedora as Advanced Server does not have the correct Kerberos support.
I was going to try disabling hyperthreading amongst other things.

Are you teaming the nics ? or what driver are you using ?

nope. everything stock, out of the box, and then a stock "everything" or "minimal" install,
which in this case means tg3 for the nic driver.
I've tried various things, turning off hyper threading, etc etc. not much luck
I guess I need to find the time to set it up to get debugging output when it
chokes.

We have 2550's that exhibited the problem of the system locking up tight ar random times after bootup. This was with RedHat Linux 8.0 running on them and we fixed it by adding 'noapic' to the kernel command line in the grub.conf file. Our 2650's have RedHat Enterprise 3.0 running on them and they don't seem to exhibit the same behavior.
Hope this helps,
Doug
