Does the laptop have a serial adapter?
If not, I don't know how to debug that (There will be firescope to
redirect kernel output over firewire, but that is future).
If yes, connect the machine over a crossed serial cable with another
one. On the remote machine watch the serial output with e.g.
screen /dev/ttyS0 57600
On the machine that gets debugged add the kernel option
console=ttyS0,57600
You should now see the kernel messages popping up on the remote screen
session.
Try to boot a SuSE debug kernel.
If it does not boot you have to compile the kernel yourself:
- Install the kernel-source.rpm
- cd /usr/src/linux
- cp arch/i386/defconfig.default .config
- Edit .config and search for ACPI_DEBUG and set this line to:
ACPI_DEBUG=y
- make
- make install modules_install
- mkinitrd
- add a new boot entry for the kernel/initrd in /boot/grub/menu.lst
- reboot
Now you can enable extended ACPI debugging (carefully, not too high):
echo 0x1F >/proc/acpi/debug_level
I wonder whether the machine hangs while processing some ACPI functions
and which.
Best you first search on http://bugzilla.kernel.org whether a similar
bug exists and try to help there.
If there is none, create a new one describing your problem, assign it to
the ACPI component and take me into CC, please.
Thanks,
Thomas
