Looks like a SCSI problem. The machine has an Adaptec SCSI adapter, right?

Yep, its adaptec problem

Actually i dont need AIX7XXX, since my system requires only CONFIG_FUSION.
I turned that option off, and it seems to boot fine now.

The traceback looks pretty meaningless.

What was happening on the machine before this.  i.e. was it booting up,
in which case can we have the prior dmesg file; or was the aic79xxx
driver being removed?

I can get the trace again, but basically the system was booting. 

AIC_7XXX was defined in defconfig, but my system doesnt have it. Seems like
the senario was the driver tried to probe, found nothing, and tries
to de-reg resulting in the BUG().

I will try to get the recompile and entire dmesg log in the meantime.

-mm has extra list_head debugging goodies.  I'd be suspecting a list_head
corruption detected somewhere under spi_release_transport().

Aha, looking in wrong driver ... the problem actually appears to be a
double release of the transport template in aic79xx.  Try this patch
