Hi Jürgen and thanks for replying.

I just switched to the CVS version again after running 1.13-patched for
10 days or so. Let's see how it behaves now. If I still get lockups or
firmware crashes I'll dig into my channels.conf.

Not that I have real evidence, but it seems to me (and someone already
mentioned this on the list in the past), that sometimes reloading the
driver is not sufficiant and one must reboot the machine. At least once
I had something like this:
While testing your 1.13 patches I had been running the driver with debug
enabled and reloaded the driver without debugging enabled - but I still
got some debug output, IIRC.
So maybe the instability of the last cvs attempt was caused by something
being mixed up in the cards memory or whatever.
This is all too vague, but I'll have an eye on this 'problem'.

I'll report back in a week and tell you how the current CVS driver does.

Cheers,
Juri
