Unable to handle kernel paging request at virtual address 3b617b05 ( was Re: swap_free: swap-space map bad (entry 00000100) )

[Samuel Dupas <samuel@dupas.com>]

Hi again,

I change the kernel (now 2.2.19) and I still have the same problem. It
begin by a "Unable to handle kernel paging request at virtual address"

And it strange, the machine rebooted by itself.
And after the reboot, the second disk was rebuilding (the machine is in
RAID mirroring)

Do you have an idea of the problem ?

Help would be very nice (The server is remote and I can't change hardware
easily, that's why before replacing the server I want to know what could
explain my problem)

Thanks
