Ooof. Something is broken, causing kernel to 'lock'
No oops, just nothing.

$ while true; do sleep 30; uptime; done
..
14:25:23 up 1:09, 2 users, load average: 0.12, 0.08, 0.01

14:27:24 up 1:11, 2 users, load average: 0.07, 0.06, 0.00

then freeze.


Heres the last bit of the syslog:

Im looking into it, startng with recent presentation tweaks :-/
Ill turn on whatever debug might be relevant, mutex debug included.
This is on an NFSroot setup, not that I suspect it.

Im still interested in feedback,
thanks
