Description of problem:
PowerEdge 6400 4xXeon, Perc Raid Card. Last Dell Bios
Redhat 9 with last errata ( June, the 12th 2003 )
When I type reboot or halt as root, everything goes fine during rc scripts and
during kernel stop until it tells "Rebooting..." or "Power Down." then nothing
happens. No power down or rebooting is done, the machine just stay like this.
Then, if I want my machine to stop, I have to use the power switch.
It does not happen with Redhat 8.0 on th same machine.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Install Rehdat 9 on Dell PowerEdge 6400
2.Type halt as root
Actual Results: Power does not stop
Expected Results: Power stop ;)
We do shutdown/halt by calling the BIOS APM services. On some systems they do
randomly bizarre things like work only with some kernels.
Does the same happen with the current errata kernel ?
I installed latest Erratas including kernel Erratas.
When I type 'apm', it tells : 'no apm bios found'.
The strange thing is that with RedHat 8, reboot/halt works fine.
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
