[Bug 278603] [NEW] Kernel Panic CPU Lockup, unable to handle paging request

[Carsten Menke]

Public bug reported:

Binary package hint: linux-image-2.6.15-52-amd64-server

System: Dapper Drake 6.06.2
Kernel: 2.6.15-52.71-amd64-server
Hardware: HP Proliant ML 350 G5

Since using the 2.6.15-52 Version of the Kernel I get irregular Panics.
The Problem must have appeared between release -29 and -52, as I was
running -29 for a long time without problems before.

The panic occurs 1 - 2 times a month, one time it occurred even after 2
days of uptime. It also occurs if the system is idle, as it did the last
time. The problem is that this system is in full production and due to
the panics we even got a database corruption and had to restore from
backup. Unfortunately I have read some kernel related bug reports and I
must really regret that mostly they are closed after half an year with
status "No activity" or with the notice to try the latest beta version
of ubuntu. This is really not an option, as the system is in production
the problem is real and also after half an year but  I need a solution
so stick back to 2.6.15-29.

All Firmware Updates are applied, Hardware Diagnostics run with HP's
Smart Start CD shows no errors, memtest-2.01 run over 10 hours shows
also no errors.
