Kernel panic with telnet using 2.2.2 and f771 with 2.2.3

[Marcus H. Mendenhall]

This is more of the problem I have been reporting, but have had little time
to further trace.  Look up mm->pgd in tghe mailing list archives and you
will find a log of previous discussion.  Apparently the bug is rare, so it
hasn't yet fallen on someone with enough time to track it.  However, you
have provided one _critical_ clue in the info below... you only have SCSI
disks. Also, you are on a 604e, and not a 750. I was beginning to smell
trouble in the page faults on IDE drives (I only have IDE), but since it
now is reported on a SCSI machine, the IDE driver is exonerated.
