well, even if you think it has nothing to do with the problem, now I am 
almost sure it has. Nothing is more evident than uptime:

netfinity5000:~# uptime
 21:39:39 up 21 days,  4:39,  2 users,  load average: 0,13, 0,10, 0,07

For comparison, see the last mail I added to this bug, the maximal 
continuous operation time was nothing more than about 8 days.

It would be great if anyone took care of this bug, maybe there are other 
people getting hit by this and not being able to track it down.

Would you recommend me to report this on bugzilla.kernel.org ?

Thanks and best regards,

Hans-Juergen
