Hi,

recently my kernel crashed with the following messages:

I am using 2.0.29 and the ncrBSD-Driver 1.17a. I have a ncr53c815 and a
SMC Etherpower PCI. The maschine is a Tyan Titan Pro with a PPro
200. The process 'clz' (pid 3684) is a CPU intensive user process with
some disk activity. The problem is that I can reproduce the GPF! I think
the bug is in the ext2 filesystem, the Tulip netdriver or the new NCR
driver.

Dirk

PS: Please CC: to me, I'm not on the list.
