thanks for your quick response.

I applied the patch to an otherwise clean 2.6.9-rc1-bk17, but no change to 
previous behaviour:
no oops (BUG_ON not triggered)! System boots up as normal, but just after I 
log in on the console the system freezes, i.e., keyboard does not react any 
more and the system is not accessible via network.
The time from the moment I log in to the time when the system freezes varies, 
but is in the order of 5s.
There is no difference whether NAPI is enabled or not.

My .config and the boot messages are attached to this e-mail.
