As described below, I suspected the Linuxator (due the linproc changes
last week). But eleminating all did not solve the problem.

I switched all systems yesterday morning to UP kernel - and they
are still up right now. A third SMP machine is up since 17 days with
the old sources, also SCSI and a lot of similar configs like the other both
crashing SMP systems.

Has anyone tried Tor's patch? I can not elaborate this before weekend,
because all SMP systems are heavily in use until Friday.
