First of all, thanks go to Gerard and others for their excellent work on
the sym53c8xx SCSI driver. I've been using it with great success...
until now.
I am running Redhat 5.2 with a vanilla 2.2.6 kernel on a Pentium II
platform. I have a Diamond Fireport 40 SCSI card, which contains the
SYM53C875 chipset. I am using the 53c8xx driver compiled into the
kernel, rather than as a module. The card is attached to an IBM UW
drive (sda), and also to a scsi ZIP, CDROM, and a Quantum drive.
Last night, I flashed the controller BIOS to a higher revision (4.09.06
from 4.05.00). On the next reboot, I got the following: (I could only
get one screenful, since it locked up)
SYM53C875J-0-<5,*>:target did not report sync. <== sdc is my zip drive

I thought "oops, bad BIOS" and flashed back down to the previous
revision - same problem. Checked scsi cables - same problem. Removed
all but my main hard drive (detached zip, cdrom, and scsi) - same
problem.
I *was* able to boot from a floppy, and rebuilt the kernel, for kicks,
and rebooted - same problem.
I also have an older 2.2.5 kernel, and tried that - same problem.
There was *one* time when it booted OK, but I can't think of anything
that I did differently.
I guess I can't tell for sure if this is even related to the driver,
since the GPF comes during the partition check. It was my first guess,
since I had just modified the BIOS.
Any ideas?
Thanks,
-Eric
