Hi,
I've managed to get the crash on serial console. I do break to debugger
right after the boot then try to continue and the machine panics. No extra
messages from WITNESS or INVARIANTS code. Kernel and core files are
available at:
http://www.era.pl/w3-1/vendor/kernel.debug.bz2
http://www.era.pl/w3-1/vendor/vmcore.0.bz2
I was unable to reproduce the NFS hangs so far.
/S
