Hey Robin,

Karsten had the same problem
the only one he tried on his machine that was not eventually freezing was
the current p:d kernel 
http://code.goto10.org/projects/puredyne/browser/live/kernel/config-2.6.23-rt14

using the same config moved to a more recent kernel + rt patches = freeze

but it's hard to tell what is the problem, Karsten and I have both very 
similar machines and on mine one of his "problem" config was not freezing 
at all. Maybe I should have waited longer ...?

His machine was freezing when running sc + iceweasel, and mine was fine
with Pd + iceweasel. We used the same limits.conf but he was using
rtirq.sh, not me.

Maybe we could try to see how to reproduce the freeze?

If it's the same type of freezes he had so far for different type of
kernel/config, then it's a complete system lock.
