I'm trying to boot a new Comtrade PCI 100MHz Pentium ("PA-2000"
motherboard) with a PCI NCR53c810 SCSI card and a Quantum TRB850S disk
and the kernel hangs when it tries to talk to the disk. I've tried
1.2.8, 1.2.9 and 1.3.3 kernels and they all have the same problem. The
disk works fine under DOS (for whatever that's worth) and it works fine
under Linux if I connect it to an Adaptec 1542CF in the same machine.
I've tried playing around with the PCI config and have the problem with
both level and edge interrupts. The SCSI card is using interrupt A.
I've also been playing around with debugging options in 53c7,8xx.c and
#defining DEBUG and DEBUG_INIT in scsi.c to no avail.
Today I tried putting an HP DAT drive on the 53c810. The system boots
OK, but within a few minutes of reading data from the tape it locks up.
I don't know if this is related to network activity or not (sometimes
network activity while reading the tape immediately locked up the machine,
sometimes not), although I when I was trying to boot the disk through the
53c810 I was using kernels with no networking support.
The output of the kernel when it boots (with DEBUG and DEBUG_INIT
#define'd in drivers/scsi/scsi.c and a few extra printk()'s) is below.
This output is from a 1.2.9 kernel. 1.3.3 is the same although it
doesn't have the complaints about unknown PCI devices.
Does anyone have any ideas what else I could try or what to do
next to try to debug this problem?

[ This is where it dies. Sometimes it finishes printing that last
message (which is supposed to be "Leaving scsi_do_cmd()" and
even gets through another printk() I added after the first
call to scsi_do_cmd() and sometimes it dies in the middle of
the message. In either case, they keyboard and machine are
completely dead and I have to hit the reset button to reboot. ]
