Boot on battery + lapic

System hangs first at "[    0.273000] NET: Registered protocol family 2";
pressing a button the start goes on. 
Second hang at "[    0.838000] scsi1 : sata_sil";
Here I plugged shortly ac-cable in and removed it again.

Does booting w/ clocksource=acpi_pm avoid the problem?

Comment 15 Thomas Gleixner 2007-03-21 07:40:11 UTC
Patch to disable local apic timer on the kernel command line solved the problem.
The final patch detects the known broken nx6325 via dmi quirk and disables the
local apic timer on those systems.
