Description of problem:
kernel: SCSI subsystem driver Revision: 1.00
kernel: aic79xx : PCI 3:2:1 MEM region 0x0 unavailable
Cannot memory map device
nvram-scb == 0xfe
SCBPTR == 0xff
Signature = BIOS
Version-Release number of selected component (if applicable):
kernel-2.4.20-8smp plus kernel-2.4.20-8 and kernel-2.4.20-9smp
Steps to Reproduce:
1. start up
Adaptec SCSI Card 39320D
You are best off using the 1.3.8 driver for Justin Gibb's website:
Red Hat has not been responding to bug reports on this driver for some reason.
Also, the kernel has gone through several errata releases without a single
update from the 1.0.0 driver which is EXTREMELY unstable. This problem
currently exists in 7.x, 8.0 and 9. 2.4.20-13.x is still at 1.0.0.
Any response would be nice, Arjan or Brian. "1.3.8 will be out in the next
errata" would be ideal. What is holding this up?
We will eventually look at updating this driver when Adaptec manages to do one
that doesn't break aic7xxx as well and we can test it good enough.
I'm considering taking the one from 2.4.21-rc2 because that one is at least
FWIW, we experienced the same issue. Driver would start fine, but Linux always
rebooted when scanning the bus for disk drives. Getting 1.3.10 (latest) from
Justin's site fixed the problem for us, at least for now.
Of note, this driver in 2.4.20-19.9 does not work for the following card:
03:02.0 SCSI storage controller: Adaptec: Unknown device 801d (rev 10)
Subsystem: Adaptec: Unknown device 005e
Flags: bus master, 66Mhz, slow devsel, latency 64, IRQ 28
I/O ports at 4400 [disabled] [size=256]
Memory at fc300000 (64-bit, non-prefetchable) [size=8K]
I/O ports at 4000 [disabled] [size=256]
Expansion ROM at <unassigned> [disabled] [size=512K]
Capabilities: [dc] Power Management version 2
Capabilities: [a0] Message Signalled Interrupts: 64bit+ Queue=0/1 Enable-
Capabilities:  PCI-X non-bridge device.
Installing the kernel from severn enables this device to work, or installing the
drivers from http://people.freebsd.org/~gibbs/linux/.
See bug #100884 for more info regarding device 0x9005 0x801d.
I too get the "kernel: aic79xx : PCI X:X:X MEM region 0x0 unavailable" message
Currently we running on RH9's latest kernel errata (2.4.20-20.9smp).
It seems as of now the latest version of Justins driver only has prebuilt
modules for 2.4.20-18smp so I'm down-grading and trying my luck.
Our system boots but we're getting lockups in the night for no obvious reason.
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
