Ran into this on the first cold boot into this kernel from a clean shutdown
last night. I grabbed a boot dump if anyone is interested. Havent seen
the crash again but wont be trying to reproduce any more unless someone
asks, since this machine was only booted to test Hennings sk(4) checksum
diff.
FWIW, I did another cvs update and kernel recompile prior to my sk(4)
tests. Since it only happened once, and appears to have crashed in
fsck/uvm code rather than network/device code, I didn't mention it then.
Apologies if this causes more confusion.
Thanks.
