Description Andrew Gormanly 2006-02-27 14:44:26 UTC 
Description of problem:
When using the installation CD in an attempt to recover a crashed machine, the
kernel panics on attempting to read the machine's hard disk.

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


How reproducible:
Every time

Steps to Reproduce:
1. Boot from installation CD
2. Mount hard drive
3. Read hard drive
  
Actual results:
Kernel panics

Expected results:
Able to read and modify data on disk

Additional info:

This happens with RHEL 4 CD1, for the original release CD, Update 2, and the
latest beta of Update 3.

The error message (using rescue mode, though this happens on attempts to do an
upgrade install too) is:

sh-3.00# Kernel panic - not syncing: drivers/ide/pci/piix.c: 394: spin_lock
(drivers/ide/ide.c: c037bb68) already locked by drivers/ide/ide_ops.c/1234

with Update 2 - with the original disk set, it is:

sh-3.00# Kernel panic - not syncing: drivers/ide/pci/piix.c: 390: spin_lock
(drivers/ide/ide.c: c036b8e8) already locked by drivers/ide/ide_ops.c/1234

and with the beta of U3 it's:

sh-3.00# Kernel panic - not syncing: drivers/ide/pci/piix.c: 396: spin_lock
(drivers/ide/ide.c: c037dd68) already locked by drivers/ide/ide_ops.c/1234

This bug is not found when using the Fedora Core 3 or 4 (release) CDs.

Hardware is a Super Micro P6SBA motherboard and a Seagate ST340015A hard disk
and a CDR-8428B CD-ROM.
