Description Steven Pritchard 2004-01-27 18:35:46 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1)

Description of problem:
The SMP kernel panics very early on while booting on a dual Opteron
240/Rioworks HDAMA system.  (I have no scrollback or serial console to
determine the point where the panic happens yet.)  The UP kernel boots

Also tested with identical results on 2.4.22-1.2163.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. On a fresh install of FC 0.96/x86_64, boot the SMP kernel.

At what point in the boot does this happen?  Any chance of getting a
serial console soon?

Comment 2 Sam Varshavchik 2004-02-04 12:10:12 UTC
I hope to get to it soon.  I'm working on the box, trying to resolve
other showstoppers first.

Comment 3 Sam Varshavchik 2004-02-05 05:03:34 UTC
The kernel panics right after initializing CPU 1 on this Dual Opteron.

The call trace in the panic includes some symbol information, without
the benefit of ksymoops.  The panic occurs in:  set_cpu_allowed+411.

The next entries in the call trace are:   free_uid+2, ksoftirq+77,
child_rip+8, ksoftirq+0, child_rip+0

Code: 8b 4b 3c 48 69 c9 ...

Still working on a serial console, to capture the whole thing,
hopefully the above may be helpful in the meantime.

Comment 4 Sam Varshavchik 2004-02-06 02:48:17 UTC
I have the serial console attached; however it looks like the SMP
kernel does not panic consistently.  I've been able to boot the SMP
kernel a couple of times already, with the serial console attached.

I will keep the serial console available, and update this bug when I
capture a panic.

Comment 5 Sam Varshavchik 2004-02-11 02:46:44 UTC
After some additional testing I cannot reproduce the bug after
updating to kernel build 2.4.22-1.2166.nptlsmp and flashing the
motherboard to the latest OEM BIOS.

There does appear to be a residual problem with the aic79xx.o module
(I can crash it fairly reliably), but that's going to be a different bug.
