After upgrading to 2.6.8.1-mm1 from plain 2.6.8.1 my machine does not
boot anymore. The last message i see is:

ACPI: Processor [CPU0] (supports C1,C2,C3, 8 throttling states)

In plain 2.6.8.1 the next messages would be:

ACPI: Thermal Zone [THRM] (52 C)
Console: switching to colour frame buffer device 175x65
Linux agpgart interface v0.100 (c) Dave Jones
agpgart: Detected SiS 648 chipset

Booting with acpi=off works fine. I have also tried pci=routeirq but
it
does not make any difference.

The machine is an Asus L5c laptop.

Please try booting with "pci=routeirq"
If that doesn't work, please take stock 2.6.8.1 and apply the latest
patch here:
http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/release/2.6.8/
and give it a go.

This will bring your kernel up to the same ACPI patch that is in the -mm
tree, but without all the other stuff in the mm tree.

If it fails, then ACPI broke. If it works, then something in -mm broke
ACPI.


Hi,

I did what you suggested but the kernel still hangs. I have put the
details on bugme.osdl.org:

Could you try the patch included in <http://bugme.osdl.org/show_bug.cgi?id=3191> as it fixes my L3C and the analysis of the problem may well lead to an ACPI crash...
