Description Michel Alexandre Salim 2002-10-07 05:13:57 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20020830

Description of problem:
I have a dual-Athlon MP system; if I boot into the SMP kernel or Windows and
then do a warm reboot into the UP kernel *immediately without entering BIOS*
everything works fine.

However, if I do a cold-boot into the UP kernel, or entered the BIOS prior to
booting the UP kernel, I get stuck in 'Configuring kernel parameters' - not
hung, since I can type anything, but CTRL+ALT+DEL does not work.

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

How reproducible:

Steps to Reproduce:
1.Boot into UP kernel after booting another kernel (SMP, Windows, etc)
2.Boot into UP kernel after booting another kernel, but enter BIOS setup first
3.Cold boot into UP kernel

Actual Results:  after (2) and (3) boot process stop at 'Configuring kernel
parameters' - i.e. it would not set the system clock

Expected Results:  Boot process proceeds normally

Additional info:

Motherboard: ASUS A7M266-D
CPU: 2xAthlon MP 1600+ (1400 MHz)

Tried turning on/off every single BIOS options related to SMP, no effect. Did
not notice problem before flashing BIOS from revision 1004 to revision 1008
yesterday, but this Linux install was done two days ago so probably I never
booted straight into UP before then (had to because my WLAN network card is
unstable under SMP)
Comment 1 Warren Togami 2002-10-07 12:49:22 EDT
I think this kernel disabled APIC for Uniprocessor machines to workaround Bug
62295 which prevented several mobile Atlon laptops from rebooting.  Try
recompiling the current Athlon UP kernel config with this option re-enabled.  I
don't know if this would help, but I think it may be related.

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
the bug tracker at: http://bugzilla.fedora.us/
