Hi,
I was just reading my news with tin on this 64MB P100 ASUS TP4
FreeBSD2.1r machine (no load) when suddenly following scrolled
in my face. ;-((( ( I was not amused )
I've been seeing this a couple of times on our machines since
we installed a new site wide kernel. I have appended the
dmesg output after the crash and the diffs from GENERIC to
my kernel config.
Could it have to do with the berkeley packet filter bpf
I recently added to our kernel config ? I never had that
in there before. Apart from that I have removed the wd* devices
and added the cy0 driver.
I'd be thankfull for any pointers.
Greetings
Christian Kratzer
