[Users] Kernel oopses on 2.6.24 + ovz005.1

Tue Jun 17 09:04:08 EDT 2008

Hi,

I'm seeing a number of these oopses in which a process that was
somewhat busy gets killed, on a 2.6.24 + ovz005.1 (custom compiled but
no other patches). See below. So far no kernel panic, but obviously
useless for a production setup.

The machine is 4-way quad-core Opteron, recent build. Do you need more
information? (lspci output attached)

Suggestions to fix this would be much appreciated. Failing to fix
this, I'd be patching Areca drivers on latest 2.6.18 OpenVZ kernel to
be able to use this box, but would really prefer to get the new
release working instead.

Regards,
Jan
