SMP 2.1.90-pre3 SCSI kernel panic

Machine: SMP kernel pre-90-3 + dual PII + aic-5.0.7 patch +
integrated AIC-7895 Dual Ultra SCSI + Tyan Motherboard

2.0.33 UP kernel works flawlessly. 2.0.33 SMP locks hard randomly, even
with a BusLogic Flashpoint card instead of the Adaptec one.

Since 2.1.89, including pre90-[123], SMP kernels keep hanging a later
after getting this messages:

Last message is a kernel panic. I even get messages complaning about
insufficient disk space, but there´s free space.

Any hints?
I can turn on scsi debugging and try to catch that bug with some help.
