2.6.0-test9-bk12 oops in file_ra_state_init

[Greg KH]

Ok, this laptop doesn't seem to like to stay up on a 2.6 kernel for more
than a few days.  Usually it locks up overnight and I can't catch any
oopses, but this morning I caught the following:

Unable to handle kernel paging request at virtual address 050d0000
 printing eip:
c013ab39
*pde = 00000000
Oops: 0000 [#1]

Which then spireled off into lots of other oopses, all in the same file
at the same location.  Then these fun messages:

attempt to access beyond end of device
hda6: rw=0, want=2195953118, limit=20482812
Buffer I/O error on device hda6, logical block 3245460206

hda6: rw=0, want=2867041774, limit=20482812

and then two more oopses in the same location.  hda6 is my /home drive.

Anyone have any ideas?

thanks,
