Hi!
I'm using 9.1 stable svn revision 245605 and I get the panic below if I execute
the following commands (as single user):
# swapon -a
# dumpon /dev/ada0s3b
# mount -u /
# ifconfig age0 inet 192.168.2.2 mtu 6144 up
# mount -t nfs -o rsize=32768 data:/multimedia /mnt
# cp /mnt/Movies/test/a.m2ts /tmp
then the system panics almost immediately. I'll attach the stack trace.
Note, that I'm using jumbo frames (6144 byte) on a 1Gbit network, maybe that's
the cause for the panic, because the bcopy (see
stack frame #15) fails.
Any clues?
Ciao,
Christian.
