possible bug here, or maybe i'm misconfiguring.
the system is a four-way intel SC450NX with a sym53c810 on one PCI bus,
and two sym53c896a's on a second PCI bus. kernel is 2.3.39.
if i build the kernel with the ncr53c8xx driver, no SCSI problems.
if i build the kernel with the sym53c8xx driver, the system loops during
the driver's detection phase with these messages on the console:
sym53c896-1: restart (scsi reset).
sym53c896-1: handling phase mismatch from SCRIPTS.
sym53c896-1: Downloading SCSI SCRIPTS.
sym53c896-1: 0: ERROR (81:0) (3-a7-0) (0/7) @ (script 200:fe0013e0)
sym53c896-1: script cmd = 800c0000
sym53c896-1: regdump da 10 80 07 47 00 00 02 02 03 00 a7 80 01 07 09 00 c0
9a 01 08 00 00 00
-- repeat ad nauseum --
(copied by hand; serial console isn't working at the moment)
i've also seen the looping behavior with a 2.2.13 kernel built with
sym53c8xx. this kernel had booted previously, now suddenly it won't.
the "assume boards are SYMBIOS compatible" option has not been enabled.
i've also tried disabling the master parity bit, as was suggested by a
previous poster on this list, to no avail.
i'm not much of a SCSI expert, and could use a pointer. thanks!
