[should be on linux-scsi:]

Willy says the patch you want is probably:
http://linux-scsi.bkbits.net:8080/scsi-misc-2.6/gnupatch@40cf3658X57h5m24maf1efBL-aVHPw

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2.6.7 won't boot on a box with a sym53c896 scsi controller, but boots fine
on 2.6.6. Dmesg output below.

2.6.6:

sym0: <896> rev 0x5 at pci 0000:00:0b.0 irq 17
sym0: using 64 bit DMA addressing
sym0: Symbios NVRAM, ID 7, Fast-40, LVD, parity checking
sym0: open drain IRQ line driver, using on-chip SRAM
sym0: using LOAD/STORE-based firmware.
sym0: handling phase mismatch from SCRIPTS.
sym0: SCSI BUS has been reset.
scsi0 : sym-2.1.18j
Using anticipatory io scheduler
Vendor: IBM Model: DDYS-T09170N Rev: S80D
Type: Direct-Access ANSI SCSI revision: 03
sym0:0:0: tagged command queuing enabled, command queue depth 16.
scsi(0:0:0:0): Beginning Domain Validation
sym0:0: wide asynchronous.
sym0:0: FAST-40 WIDE SCSI 80.0 MB/s ST (25.0 ns, offset 31)
scsi(0:0:0:0): Domain Validation skipping write tests
scsi(0:0:0:0): Ending Domain Validation

2.6.7:

sym0: <896> rev 0x5 at pci 0000:00:0b.0 irq 17
sym0: using 64 bit DMA addressing
sym0: Symbios NVRAM, ID 7, Fast-40, LVD, parity checking

scsi(0:0:0:0): Write Buffer failure 8000002
scsi(0:0:0:0): Domain Validation detected failure, dropping back
sym0:0: FAST-10 WIDE SCSI 11.9 MB/s ST (168.0 ns, offset 31)

scsi(0:0:0:0): Write Buffer failure 8000002
scsi(0:0:0:0): Domain Validation detected failure, dropping back
sym0:0: wide asynchronous.
sym0:0:0:M_REJECT to send for : 1-3-1-5e-1f.
scsi(0:0:0:0): Write Buffer failure 8000002
....

This goes on forever - goes through all different speeds, then starts over.

Difference seems to be in 2.6.6, it says:

scsi(0:0:0:0): Domain Validation skipping write tests

but does not skip these tests in 2.6.7.

Ideas?
