| |
Good morning,
I've got an oops on a dual Opteron machine that's running on 2.6.12.3 kernel. Under heavy load the system hangs and we get this oops on the screen:
...
<ffffffff8013477d>{printk+141} <ffffffff8012db83>{try_to_wake_up+915} <ffffffff8010e445>{error_exit+0} <ffffffff80170ec6>{page_remove_rmap+38} <ffffffff80168fde>{unmap_vmas+1342} <ffffffff8016ea63>{exit_mmap+163} <ffffffff801317a1>{mmput+49} <ffffffff80136432>{do_exit+338} <ffffffff80136f5f>{do_group_exit+239} <ffffffff8010da46>{system_call+126}
Code: 41 8b 45 40 ff c8 7e 45 48 c7 83 f0 01 00 00 00 00 00 00 48 RIP <ffffffff801318f6>{mm_release+86} RSP <ffff8100daf26308> CR2: 0000000000000040 <0>Kernel panic - not syncing: Aiee, killing interrupt handler!
This problem has been described here, earlier:
http://seclists.org/lists/linux-kernel/2005/May/6369.html
Our setup is: 2x Opteron 246, Tyan Thunder K8S MB, 3ware 9500-8, 4 G RAM, Fedora Core 3 x86_64, 2.6.12.3 kernel.
Memtest shows nothing special...
Does anyone know something useful for this problem?
Thanks in advance,
Balazs
