My system is running fine with 2.0.37pre4 (RedHat 5.2), but just for curiosity I tried to install 2.2.0pre6 on my system (P166, Adaptec 2940 with BIOS 1.11).
When booting my system with the new kernel the SCSI driver fails badly to detect the SCSI devices on my system. (With 2.0.37pre4 I've no problems.)
It should print something like this on the screen (that's what I get when booting 2.0.37pre4):
scsi : 1 host. Vendor: IBM Model: DORS-32160 Rev: S84A Type: Direct-Access ANSI SCSI revision: 02 Detected scsi disk sda at scsi0, channel 0, id 0, lun 0 Vendor: IBM Model: DCAS-34330 Rev: S65A Type: Direct-Access ANSI SCSI revision: 02 Detected scsi disk sdb at scsi0, channel 0, id 1, lun 0 Vendor: SyQuest Model: SQ5110 Rev: BBA Type: Direct-Access ANSI SCSI revision: 01 CCS Detected scsi removable disk sdc at scsi0, channel 0, id 5, lun 0 Vendor: TOSHIBA Model: CD-ROM XM-5701TA Rev: 0167 Type: CD-ROM ANSI SCSI revision: 02 Detected scsi CD-ROM sr0 at scsi0, channel 0, id 6, lun 0
But instead it detects my "IBM DORS-32160" on SCSI id 1, 2, 3 and 4 (see below). Nothing is detected on id 0. The "IBM DCAS-34330" is not detected at all (worse luck, my root partition is on that drive ;-) so the kernel panics because it could not find anything to boot from.
scsi : 1 host. Vendor: IBM Model: DORS-32160 Rev: S84A Type: Direct-Access ANSI SCSI revision: 02 Detected scsi disk sda at scsi0, channel 0, id 1, lun 0 Vendor: IBM Model: DORS-32160 Rev: S84A Type: Direct-Access ANSI SCSI revision: 02 Detected scsi disk sda at scsi0, channel 0, id 2, lun 0 Vendor: IBM Model: DORS-32160 Rev: S84A Type: Direct-Access ANSI SCSI revision: 02 Detected scsi disk sda at scsi0, channel 0, id 3, lun 0 Vendor: IBM Model: DORS-32160 Rev: S84A Type: Direct-Access ANSI SCSI revision: 02 Detected scsi disk sda at scsi0, channel 0, id 4, lun 0
Another bug is:
If there's no cartridge in my "SyQuest SQ5110" (removable media drive) the SCSI detection hangs until I insert a cartridge. If no cartridge is in the drive, the kernel repeats every 5 seconds:
scsi : aborting command due to timeout : pid 8, scsi0, channel 0, id 5, lun 0 Test Uni Ready 00 00 00 10 00
With 2.0.37pre4 it doesn't matter if I've a cartrigde in my SyQuest drive or not (there's no boot partition on it... so it's not really needed for booting).
My SCSI config is:
# # SCSI support # CONFIG_SCSI=y CONFIG_BLK_DEV_SD=y CONFIG_CHR_DEV_ST=y CONFIG_BLK_DEV_SR=y CONFIG_CHR_DEV_SG=y CONFIG_SCSI_CONSTANTS=y CONFIG_SCSI_LOGGING=y # # SCSI low-level drivers # CONFIG_SCSI_AIC7XXX=y CONFIG_AIC7XXX_RESET_DELAY=5
(all other SCSI options are unset)
As I've read on this list, some other person had similar problems with 2.2.0pre5. So I justed wanted to mention that this problem still exists.
Greetings, Andreas
