>Description:
After I upgrade my HP Proliant ML110 G4 from NetBSD 4.99.51 to 4.99.52 the
machine locks up frequently. I can't provided much debugging information
unfortunately because "reboot -d" didn't work and I can't break into the
debugger because the machine only has a USB keyboard. Here are the
kernel messages:

nfs server colwyn:/export/home: not responding
nfs server colwyn:/export/home: is alive again

The NFS errors are a bit suspicious because the NFS server was running
all the time and is connected to the machine via a 1Gb/s ethernet switch.
I'm using NIS, amd(8) and an NFS mounted home directory on the machine.
I've seen lock-ups before but could never reproduce them.

The 4.99.51 kernel worked stable enough to build the new userland and
kernel with "-j 4".

>How-To-Repeat:
It happended twice while I tried to build packages and again when I tried
to submit a PR on the affected machine.

>Fix:
None provided.
