Hi all!

Here's the update, as promised (I didn't have the time to build a new
kernel until now).

Ok, i tried an unpatched 2.4.20 kernel now, which works fine and a
2.4.20 kernel with the preemption patch (same config, except for the
preemption stuff). The vanilla kernel exhibited no problems while the
kernel with the preemption patch exhibited the mentioned problem right
away.

Uhm, i don't understand much of the way the kernel scheduling, that
preemption stuff and libafs works... could it be that the client
thread is somehow "preempted" a little too long, which results in the
timeout?

Dunno...

*scratching head*

I will not use those patches for a while then, which is a pity,
because they help interactive performance quite a bit in some cases.

Kind regards

Laziness led to the invention of the most useful tools.
