(Mobile Athlon) reboot hang, IDE led stuck

Description of problem:
Rebooting Skipjack causes the Sony Vaio PCG-FXA36 laptop to be stuck at the
BIOS screen with the IDE led stuck on. It sometimes shows a keyboard stuck
error, but most of the time shows a graphical Sony logo that completely blocks
obscures the BIOS text info.
kernel-2.4.7-10.*.rpm FAILS to boot with kernel oopses.
kernel-2.4.9-31.athlon.rpm HANGS on reboot
kernel-2.4.18-0.[4-12].athlon.rpm HANGS on reboot
kernel-2.4.9-31.i686.rpm SUCCESS in reboot
kernel-2.4.18-0.[4-12].i686.rpm SUCCESS in reboot
It seems that Red Hat i686 kernel packages do not exhibit this problem, while
athlon kernel packages do. It may be notable to mention that both i586 and
athlon arch packages of Mandrake 8.2 do not reboot properly, so they may be
compiling in different options that trigger this.
Version-Release number of selected component (if applicable):
1. Mandrake 8.2 on this machine has the same problem.
2. MandrakeForum has some reports of non-laptop Athlon machines exhibiting
3. firstname.lastname@example.org owns the same model Sony FXA-36 laptop and has reported
the same problem to the Skipjack mailing list. (All current FXA series
laptops have the same motherboard chipset, but different processors.)
I forgot to mention that "noathlon" kernel option did not change test results
of the failed kernels above.

This problem did not exist in earlier athlon arch kernels. Would it be possible
for me to have access to older athlon Rawhide kernel builds in order to do
testing to find when this bug was introduced?
This page http://www.myplc.com/sony/vaio_unix_guide.htm thinks that this is a
hard drive controller issue. One guy recompiled the Rawhide kernel with
experimental ACPI and it prevented the reboot freeze. Installing the i686 arch
kernel rather than athlon arch also prevents the reboot freeze.
Still exists in Red Hat 7.3 release.
I have the same problem on 7.2 and 7.3
For now you can use the i686 kernel to avoid this reboot bug. Alternatively you
can compile yourself an ACPI capable kernel, although you will want to use the
latest 2.4.19-pre- Alan Cox kernel to have a working ACPI implementation that
I fail to see how ACPI could make *ANY* difference in this.
The only difference between the athlon and i686 kernel is how memcpy() is
APM athlon gets stuck in reboot with IDE light stuck on.
APM i686 reboots fine.
ACPI athlon reboots fine.
ACPI i686 reboots fine.
I can't explain it. I only know this through empirical testing.
Compaq Presario 700 series with Mobile Athlon or Duron processor has the same
hang in BIOS with HD light stuck on after rebooting from Red Hat athlon
optimized kernel. rpm --force installing the i686 kernel RPM fixes this problem
on this series of laptops too.
This may be more generally a "Mobile Athlon w/ certain VIA Chipset" problem.
Confirmed still hangs after reboot with athlon kernel-2.4.18-7.80, but not i686
kernel-2.4.18-7.80 of Limbo2.
Ok I think I have a handle on this, it seems you bios doesn't like the LOCAL
APIC config option, which happened to be turned on for Athlon and off for i686
Would a permanent solution in the kernel be possible, or we must always use a
the i686 workaround?
I've disabled local apic for athlon kernels too in the config, that'll be in the
kernel-2.4.18-0.75.athlon reboot SUCCESS
kernel-2.4.18-0.75.i686 reboot FAIL
kernel-2.4.18-0.75.i586 reboot SUCCESS
kernel-2.4.18-0.75.i386 reboot SUCCESS
Should close bug?
Anaconda using kernel-2.4.18-10.99 locks up after reboot. Can this fix be
applied to that kernel too?
So, looks like we still need to do something with the boot kernel, but since we
don't run separate boot kernels (per arch) not sure what the correct fix is
here. Reopening to get an answer.
Unfortionatly we can't do this for the BOOT kernel since that would disable the
workaround needed for buggy 440GX chipset bioses ;(
Reproduced this problem on the Compaq Presario 900US. This laptop has an ALi
chipset, unlike the Sony Vaio FXA series and Presario 700 series which both have
VIA. This may be indicative that this is more generally a Mobile Athlon kernel
This Presario 900 series laptop seems completely inoperative with the ALI IDE
kernel drivers, failing after over a minute of attempting to access the hard
drive or CD-ROM IDE devices. I am testing it with various other kernels tomorrow.
If the ALi problem is present in the Null beta kernel please open a seperate bug
for it and stick email@example.com in the cc line.

I have a Sony Vaio FXA47 with Red Hat 8.0 and kernel 2.4.18-17.8.0. Guess what,
systems still hangs when rebooting, displaying the Sony logo and the LED is
stuck. IF you wait some time, the BIOS eventually tells you that there was a
keyboard error. I checked the config and it says "Local APIC support on
uniprocessors" is disabled, but the problem persists.
Any chances on seeing this issue fixed?

Are you sure that you installed the athlon arch kernel?
How do I check that out?
Sorry I'm not exactly sure how to check which arch kernel is currently running.
Arjan will know.
Oh BTW, could you please read Bug 74315. Our laptops are virtually the same
except for the BIOS revision (which you can flash to be the same.) Could you
please read Bug 74315 and check if you experience this problem too?
Within Phoebe, still locks up in BIOS after rebooting from the BOOT kernel, but
athlon arch kernel is fine.
supposed to be fixed in recent kernels; apic is off for the BOOT kernel
Phoebe3's installer no longer locked up after installation. Seems fixed.
