I currently try to set up a server with an Adaptec 2810SA RAID controller.
While testing the Adaptec command line utility aacraid (actually the
command "controller list") with a vanilla 2.6.12-rc2 kernel I got the
following kernel oops - maybe someone is interested, maybe someone as
some help for me:

Unable to handle kernel NULL pointer dereference at virtual address 0000002c
printing eip:
c02e62fa
*pde = 00000000
