Hi,
When starting the system with a kernel version of 2.6.31 or later (I tested it
from 2.6.31.1 up to 2.6.33-rc3) after a while the kernel will panic with the
following message (from2.6.32.2) :

The last kernel version without this problem seems to be the 2.6.30.x (I am

Somehow nodes got mixed up or the lookup tables for pages / zones are not
giving the right node numbers.

Agreed. On this type of machine, I'm not sure how that could happen
short of struct page information being corrupted. The range should
always be aligned to a pageblock boundary and I cannot see how that
would cross a zone boundary on this machine.
Does this machine pass memtest?
Is there any chance the problem can be bisected?

I ran one pass with memtest86 without errors before posting this bug, but I
can let it run "all tests" for a while just to be sure it is not caused by
broken hw.

I will give it a try, when the memtest is done.
Thanks.

Please disregard this bug report. After running memtest for more than 10 hours
it found a memory error. The funny thing is, linux found it much faster...
Thanks for your time.

I'm sorry to hear it but at least the source of the bug is known.

It could be that your power supply is slightly too inefficient and the
errors only occur when all cores are active or all disks - something
Linux might do easily where as memtest does not necessarily stress the
machine enough for the power drop to happen.

Thanks for testing and getting back to us.
