AIC7xxx kernel problem with 2.4.2[234] kernels
From: Stephen Smoogen
Date: Fri Jan 16 2004 - 17:09:44 EST
I hope this is in the correct mode and I am sending it to the correct
list :). Please let me know what other information I need to supply.
[1.] One line summary of the problem:
Booting problems with aic7xxx with stock kernel 2.4.24.
[2.] Full description of the problem/report:
I think I am seeing the same problem that was reported to the list from
Moal Tanguy on 2003-09-08. Our oem systems use an older SuperMicro
motherboard with a built on aic7xxx Adaptec aic7892 Ultra160 SCSI
adapter. Most of the systems have a forward mounted 'removable' 18
gigabyte scsi disk drive (different manufacturers). When running any Red
Hat kernel we have no problems booting the system. When using 2.4.22,
2.4.23, or 2.4.24 kernels, the system loads in the aic7xxx module from
the initrd and probes the interfaces. In systems with multiple disks, it
reaches the first drive (the removable disk) and errors out with a slow
progression of
Unexpected busfree while idle
SEQ 0x01
After 10 or so of these, it will then go merrily onto the next disk
without reporting any errors, and then 'crashes' because it was unable
to find the root directory to continue.
Interestinglyu, after this has happened using the hardware reset will
cause the system to not be able to find the SCSI ID0 disk to boot
from. A complete power cycle is needed for the SCSI controller to find
the disk again.
Patched 2.4.24 kernel with latest items from Justin Gibbs website, and
problem occurs in same form. From what I could google, I am expecting it
is hardware related in some issue, but would love to know what.
