Description Dominique Michel 2007-04-04 04:03:31 UTC
I know at it is not a mainline or mm kernel, but Sergio Montero on
linux-acpi@vger.kernel.org asked me to fill a bug repport.

Most recent kernel where this bug did *NOT* occur: hard to say. The problem is
at my older kernels didn't use ACPI, but since rt patch 2.6.18-rt6, I need ACPI
to get the pm_timer as provided by ACPI to use as clock source.

I get strange things with this hardware for a long time ago. With a stock agnula
kernel (2.6.14-1-multimedia-386), 2 modules was loaded at boot time for my
chipset: the SIS5513 correct one and a VIA82C if I remember well. (It was a via
module in any case) This kernel was hanging very often and the only cure was to
do my own kernel without the via module.I didn't get this problem with the
preceding agnula version with kernel 2.6.12-1-multimedia-386

I also get an error in dmesg with the ACPI_BUTTON and BLK_DEV_GENERIC=yes.
BLK_DEV_5513 was a module (kernel-2.6.20-rt8). I removed BLK_DEV_GENERIC and put
BLK_DEV_5513 inside the kernel and I don't get this error anymore.

It is with the last bios revison, 1005.

With a 2.6.19.1-rt15 that have antother configuration and work fine, I get
when running it with pci=noacpi:

I am trying to run the 2.6.20-rt8 with noapic and nmi_watchdog=0. I get:
# cat /proc/interrupts
           CPU0

I also redone the kernel config from scratch with this 2.6.20-rt8. I try first
without noapic and it hanged after 2 days, so I am trying now with noapic.

Problem Description:
I really want to use CONFIG_X86_PM_TIMER in the ACPI config. The problem look
like the ACPI is assigning shared IRQ and rt kernels don't like it. It freeze
from time to time. Sometime after a few hours, sometime after a few hours. I
also don't know how to reproduce it, it just hang when it hang. I try to add
some debug stuffs in the kernel but cannot see anithing wrong in dmesg.


Steps to reproduce:
1) Boot with ACPI enabled.
2) Wait until it hang
3) It doesn't seem to matter if the system is quite or heavily loaded. I get
some hangs when burning a CD and having the network and the proc heavily loaded
with amule at the same time. I also get some hangs when only X, fvwm and a gnome
console was running.

kernel config

My current kernel config. The system freezed yesterday with it. I am currently
testing if booting with "noacpi" help.

Unfortunately, it was just frozen again with "noacpi" when I come back from a walk.

Is it something more I can do?
Comment 5 Roland Kletzing 2008-01-27 08:18:53 UTC
have a look at sysrq http://lxr.linux.no/linux/Documentation/sysrq.txt 

if the local console isn`t useable due to freeze you may redirect kernel message to external attached serial console and trigger sysrq from there. thereĀ“s many information on the net how to setup

for me she showed up one time in the floor of hour, however as a result of this problem I lost a mysql database - mysql innodb not start - "Accertion error" - did not help even "innodb_force_recovery = 4", backup was an a week remoteness - the works of whole department lost data for a few days, the management simply in shock - I going to discharge from job (((

this problem already whole year:
