2.6.8 + SMP + dac960 problem

[David Monro <davidm@amberdata.demon.co.uk>]

Hi,

I've just acquired a DS20 with 2 cpus and a couple of dac960 
controllers. Done a debian base install from the latest netinst release 
candidate, all worked fine (except it didn't find the cd drive on the 
sym53c8xx controller until I loaded the module manually). Then I 
installed the 2.6.8 smp kernel kernel (2.6.8-1-smp off the cd, but also 
see exactly the same problem with the latetest  2.6.8-2-smp  package, 
2.6.8-7). It hangs striaght after printing the banner:

The 2.6.9-2-generic (uniprocessor) works  fine:

and the machine comes up fine.

Anyone seen this before? Anyone have an SMP  box with a dac960 working 
with the
latest kernels?

Cheers,
