Problem with aic7xxx driver and SMP (fwd)

[tarquin at texas.net]

System: Chaintech P6DBU with onboard 7890 Ultra2 controller

Driver versions: 5.1.4, 5.1.6, 5.1.10.
Kernel 2.0.36, 2.1.131-ac13, 2.2.0pre7-ac4

Problem: UP 2.0.36 works fine. SMP 2.1.131-ac13 with .4 and .6 puts insmod
into uninterruptible, as does 2.2.0pre7-ac4 with .10.

scsi0 in this case is the same card, with a hung insmod. This is a recently recompiled driver with verbose info. loaded with insmod -v aic7xxx.o -m -o newaic aic7xxx=verbose:0x1ffff.

Symptoms: machine locks at last line when compiled into the kernel proper. 
insmods hang in uninterruptible sleep. Occurs with 5.1.4 on a SMP 2.1.131-ac13,
5.1.6 on SMP 2.1.131-ac13, and 5.1.10 on SMP 2.2.0pre7-ac4.

Right now the SCSI bus is completely empty, just the card and cable to the 
external jack. I should have a CD burner soon to test more, but it looks like
it's some obscure thing having to do with SMP.
