Looking over the archives for the last few months, I see a number of
people reporting various problems with aic7xxx controllers and 2.4.4/2.4.5
kernels. So here's the information on my 2.4.5/aic7xxx problems.
This problem manifests both with a custom 2.4.5 kernel and the stock
Debian 2.4.5 image. I know my version has internal SCSI and SCSI disk
support and assume the same is true for the stock image; this shouldn't
just be a problem with modules not being loaded.
On boot, the system fails thusly:
SCSI subsystem drive Revision: 1.00
scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.1.13
<Adaptec aic7899 Ultra160 SCSI adapter>
aic7899: Ultra160 Wide Channel A, SCSI Id=7, 32/255 SCBs
<various non-SCSI-related items>
NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.
request_module[block-major-8]: Root fs not mounted
VFS: Cannot open root device "801" or 08:01
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 08:01
Also of potential interest, 2.2.19 detects and displays information for
two SCSI channels, while 2.4.5 only appears to see one.
Here are all the (obviously) SCSI-related options which are set in .config:
CONFIG_SCSI=y
CONFIG_BLK_DEV_SD=y
CONFIG_SD_EXTRA_DEVS=40
CONFIG_SCSI_DEBUG_QUEUES=y
CONFIG_SCSI_MULTI_LUN=y
CONFIG_SCSI_CONSTANTS=y
CONFIG_SCSI_LOGGING=y
CONFIG_SCSI_AIC7XXX=y
CONFIG_AIC7XXX_CMDS_PER_DEVICE=253
CONFIG_AIC7XXX_RESET_DELAY_MS=5000
I'll be happy to supply any further information which might be useful,
but I don't know that there's much else to tell, given that it's failing
before any sort of logging starts up.
