Even though you don't care anymore, whether or not the Jaz is upsetting
the card or driver by spewing garbage is easy to determine: with nothing
plugged into your bus adapter, does the rescan still lockup your
machine?  And while we're talking about it, is the lockup a real
lockup, or is it simply that the camcontrol process hangs and you have 
it in your startup sequence in such a way that the boot is not able to 
continue?

Also, did you do the obvious things like trying the aic on different
interrupts [well, at least both of the interrupts that you stated you
use with other devices successfully]?  In your second(? third?)
message to the -scsi list, you sent the following (snippets from) dmesg:

>aic1: <Adaptec 6260/6360 SCSI controller> at port 0x340-0x35f irq 3 slot 0 on pccard0
>aic1: aic6360, dma, disconnection, parity check
>(probe0:aic1:0:0:0): ccb 0xc0b3c000 - timed out, phase 0xa6, state 1

I'm not sure about yours, but my 1460B does not list irq 3 as one of
the valid IRQ's that it can generate.  Check "pccardc dumpcis" and
search for IRQ.  While "timed out" messages could also be cable/device
related, on my setup they indicated an IRQ conflict.

For what it's worth, 5.0-CURRENT + SMP 2xPII + SlimSCSI 1460B (irq 9) + Iomega 
Zip works.

Apologies in advance if this was meant to convey that you are no
longer interested in resolving this problem.
