Aiee, killing interrupt handler!

[Hawk Xu <hxunix@gmail.com>]

Hi!

Our server(running Oracle 10g) is having a kernel panic problem:

And, we have these error messages in the /var/log/kernel file:

The kernel version is 2.6.12.5.  The kernel panic problem happened 3
times last week, and we don't know whether there are some relationships
between the kernel panic and the error messages in the kernel log file.

That's all we know now, the server is in Nanjing, which is 1000
kilometers south of us, and we are not allowed to access the server.

Any help would be great!


Best regards,

hxu
