Unable to handle kernel paging request, 2.6.16.25 server reboots

[Jim Klimov <klimov@2ka.mipt.ru>]

Hello linux-kernel,

  A file server reboots casually (about once a day), possibly after
  a hardware change and/or kernel upgrades. Messages from netconsole
  from some prehistory till when it died.

  Possibly there's some roughness in new 3Ware controllers and two
  dozen harddisks on a 1200W power source, or it may actually be
  something in the kernel?

  Tell me if i need to send any more details to help find the cause?

  PS: why is the kernel time so strange during boot messages?
  It resets at least 3 times before point zero...
