The first register dump I got when I tried to rpm -Uvh kernel-headers.
I however believe that it was not caused by the package but by the
overall activity on the system -- on rpm, one make, one lmbench.
I still believe that I do not deserve a register dump ;-) I'm rewriting
the numbers from paper, so there will be mistakes, I'm sure:

Scheduling in interrupt
page fault from irq handler: 0001

Cause 0000000c
Aiee, killing interrupt handler

This run across the scrren for some while, then it stopped. The
previous copies seemed still the same -- at least at a glance.

The second dump I got when compilling ssh, going some ftps and ssh.

after which one line

kmem_free: Bad obj addr (objp = 88ebe430, name=signal_queue)

and then another 30 or so lines of

kmem_free: Bad obj addr (objp = 00000007, name=signal_queue)

This is 2.1.100 from HH 5.1 PR distribution, R4600PC, 32 MB.

The register lsitings wouldn't bother me if they did not crash my
machine at the same time ;-)
