Dear maintainers,
The following problem, I posted in this list in July 8, has _not_ been fixed
in 2.0.35. Symptoms are still the same: panic as the scsi harddisk is not
detected. The yamaha cdrom, however, is detected. I'm back at 2.0.33.
Thought you might want to know.
For details see the old message (shortened) below.

Dear maintainers,
I'm having trouble with the aic7xxx driver in 2.0.34. The same in 2.0.33
works without a problem.
I'll be able to do some testing if needed, please let me know.
Hardware: Adaptec 2940 SCSI PCI
- Quantum harddisk id 2
- Yahama cdwriter id 3
- Iomega jaz id 6
- (card itself at id 7)
Other possibly relevant hardware: ide zip drive, internal 1k44 modem on irq 5.
Kernel config (2.0.34):
#
CONFIG_SCSI=y
#
# SCSI support type (disk, tape, CD-ROM)
#
CONFIG_BLK_DEV_SD=y
# CONFIG_CHR_DEV_ST is not set
CONFIG_BLK_DEV_SR=y
CONFIG_CHR_DEV_SG=y
#
# Some SCSI devices (e.g. CD jukebox) support multiple LUNs
#
# CONFIG_SCSI_MULTI_LUN is not set
CONFIG_SCSI_CONSTANTS=y
CONFIG_SCSI_AIC7XXX=y
CONFIG_AIC7XXX_RESET_DELAY=15
rest commented
During kernel boot I get:
scsi: 1 host.
(scsi0:0:-1:-1) Scanning for devices.
scsi: detected total.
which is obviously nothing.
Since the harddisk contains the root filesystem things go wrong lateron:
VFS: Cannot open root device 08:02
(is /dev/sda2, whisch is correct)
Kernel Panic: VFS: Unable to mount root fs on 08:02
(of course, disk was not found)
(scsi0:-1:-1:-1) Bad scbptr 255 during SELTO
(scsi0:-1:-1:-1) Referenced SCB 255 not valid during SELTO
SCSISEQ = 0x12 SEQADDR = 0x9 SSTAT0 = 0x15 SSTAT1 = 0x88
[...]
Thanks for any pointers on this!
NOTE: PLEASE REPLY TO ME DIRECTLY, I'm not on the list.
