Description Chuck Buda 2006-02-01 19:11:07 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8) Gecko/20051111 Firefox/1.5

Description of problem:
We received an IBM x260 server with a Adapter AIC-29320ALP SCSI Controller.  There are no RHv4 device drivers for this device.  Kudzu and the OS do not see this device.  However, after updating the system, kudzu suddenly "finds" the device and asks if I want to configure it.  When I do, the system hangs.  The last message seen is "Starting HAL Daemon     [OK]".  The system can be rebooted to Single User mode but removal of the device from the hwconf file does not fix the problem.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.  Load RH Enterprise AS v4 on system.
2.  Run update2.
3.  Reboot system.
4.  Let kudzu configure the device.
5.  Watch system hang.

Actual Results:  See Description.

Expected Results:  System should have booted to multi-user level.

If you enable sysrq (kernel.sysrq=1 in /etc/sysctl.conf), and, when it hangs,
hit 'alt-sysrq-t', what does it print? (alt-sysrq-p may also be useful.)

Made the change to /etc/sysctl/.conf and rebooted the system.  It hung again and
I hit the 'alt-sysrq-t' and 'alt-sysrq-p" ket sequences with no results.  The
server did nothing.

I've removed the SCSI controller, reloaded the OS, ran update2 to bring it to
most current level.  System ran for over 15 hours before problems began.  I
tried to load an rpm package from a floppy disk.  System did not automount the
floppy disk.  Tried a manual mount which did not work.  Rebooted system and
original problem returned -- bootup display shows that the HAL daemon is being
started up [OK], then system froze.
Tried hard reboot.  System ran through BIOS startup fine.  It now froze after
saying that it had uncompressed Linux.  
Now what?

The problem was found to be a hardware problem.  Sorry for the trouble.
