Kernel message

[Marcus H. Mendenhall]

This appears (from the mm->pgd reference) to be the same crash I have been
seeing and posting to the list for a while.  I have been trying to trace it
down, but not with much success.  It comes from mm/slab.c and may be
associated with a bad page fault.  Very few people (other than me) have
been reporting it.  I am seeing it on a G3 rev 2 with 128 MB RAM, running
off the stock internal IDE drives.  A possible indication is that it might
be a bug in the IDE driver, causing page fault to fail, since at least one
person running with SCSI drives has indicated he is not seeing this
problem.

Unfortunately, the time I can spend chasing this is small, so unless
someone with a lot more time starts getting annoyed by it, it won't go away
soon.
