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):
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?
I hope to get to it soon. I'm working on the box, trying to resolve
other showstoppers first.
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.
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.
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.
This bug can be closed.
