Curious that this happens
1. only on 2.6
2. with acpi=off and "acpi=on"

Would be good to know that the system is running the latest BIOS.

cheers,

yes, but true: any other reboot code I've come across (including
those of the other Linux kernel versions) work as expected on the box.

yust retested it with the latest (2.6.4) kernel -- yes, regardless of
which (or none) powermanagement is used, the reboot freezes the mashine.

afaik I'm using the latest available BIOS for the board.

btw. the toppic is false, that should be 
"Kernel 2.6.x reboot hangs on AMD Athlon System"

also try with noapic boot option. It was supposedly fixed (cause a
problem with my system) but may still causing problems for you.

Just tried that, no effect...  :-(

Something must be strangely different between the way 2.6.x tries to
reboot the System and any other Kernel-version does.  Who is the
Maintainer of this code?  Or maybe even better, who did the changes,
made to the reboot-code in 2.6?  (There is a ne file reboot.c, but
without any author notice)

Please cc me in any reply, I'm not subscribed to the lkml.

Kernel 2.6.2 reboot hangs on AMD Athlon System

[Sascha Wilde]

Hello,

I have a strange Problem with all 2.6.x kernels (and only with
these): my box refuses to reboot.


The Problem:

All versions of Linux 2.6.x (I started testing with 2.6.test6 and the
latest version I tied was 2.6.4 release) cause my System to hang when
I try to reboot (or power off).


The Hardware:

The system in question is a x86 PC with:
AMD Athlon(tm) Processor stepping 02 CPU (classic 800MHz)
AMD Irongate chipset 

This list is quite short, for I have no idea which components could be
related to the problem.  I will provide you with any further
information needed or send you a full kernel startup log if wanted.


What I tried:

The problem occurs at the end of any shut-down process, right when
the system should reboot (or power off).  I tried different Kernel
versions (form 3.6.test6 to 2.6.4) using different compiler
tool-chains and configurations.  It also tried a kernel 2.6.1 from a
"Knoppix" CD distribution, so this is unrelated to my compiler.

I tried booting into single user and rebooting via sysreq-keys, it
made the machine hang, too -- so I would say the userland is not
involved.

During digging in the dark I also tried different power-management
configurations with APM and ACPI, no chance (normally I use APM).

This is only a 2.6.x matter, all earlier Kernels I used (including
some 2.2.x versions and nearly every 2.4.x version), the netbsd
kernel (1.6.1 and 1.6.2) and the grub bootloader are able to reboot
the system as expected.


This problem is 100% reproducible on my box, but I haven't yet found
any other system showing this symptoms.

Sorry for this very vague report, but I have simply no idea, what
might be the cause.

Please CC me in any answers, I'm not subscribed to the lkml.
