SubjectPossible problems with khub in current 2.4.15-2.4.16 kernels
I've noticed an odd occurance with the 2.4.15 and 2.4.16 kernels during
testing.

There seems to be a problem with khub.c or it could be my hardware but
I keep getting the following oops and ptrace about 50% of the time
during boot. The following snip is from the boot log of the 2.4.16
kernel compliled this afternoon.

If anyone has any ideas or a suggested fix.
