Description of problem:
When booting FC4 i386 on the IBM HS20 8832 blade, the machine hang when starting
the last line printed on the console is 'running /sbin/loader'. You see a flash
where the display goes black and comes back and that is it.
ALT key sequences to switch VT have no effect
booting with acpi=noirq allows the installation to succeed
Version-Release number of selected component (if applicable):
every time, unless acpi=noirq or acpi=off is specified
Steps to Reproduce:
1. attempt to install HS20 8832 blade with FC4
hang when starting anaconda, unless acpi=noirq is specified
acpi=noirq should not be needed
This is the IBM HS20 blade with dual Intel Xeon x86 processors.
It has optional support for IDE-RAID (LSI MegaIDE) which can be enabled/disabled
in the BIOS.
With RAID disabled, the disks look like regular IDE drives.
The problem is the same with IDE-RAID enabled or disabled, when acpi=noirq is
not passed, although when it is enabled the kernel boots very slowly with lots
of 'lost interrupt' messages from the IDE drives.
With acpi=noirq the install works for both the non-raid and the raid mode

[This comment has been added as a mass update for all FC4 kernel bugs.
If you have migrated this bug from an FC3 bug today, ignore this comment.]
Please retest your problem with todays 2.6.12-1.1398_FC4 update.
If your problem involved being unable to boot, or some hardware not being
detected correctly, please make sure your /etc/modprobe.conf is correct *BEFORE*
installing any kernel updates.
If in doubt, you can recreate this file using..
mv /etc/sysconfig/hwconf /etc/sysconfig/hwconf.bak
mv /etc/modprobe.conf /etc/modprobe.conf.bak
I installed the updated 2.6.12-1.1398_FC4 i686 SMP kernel, and removed
acpi=noirq from grub.conf and rebooted.
The system came back up without any problems, so this issue can be closed.
