Hi, I'm running -CURRENT on an i386 box where it runs marcus@'s
tinderbox. (Ports building similar to pointyhat.) Since my last update
on June 4 I can't get through an entire build of all ports without a
kernel panic. Below is the backtrace from the latest crash. It only
happens while building ports in the tinderbox and it happens fairly
reliably. I think the NFS usage between this box and the OpenBSD 3.6
NFS server is bringing this bug out. Please let me know if I can
provide anything else. Thanks.
Tom
