| |
Hi!
If the ac-cable is plugged in, I can start my Notebook (HP nx6325) without any problems. On battery the kernel hanging around and it takes "hours" to boot the kernel and the system is *very* slow. For example an init-skript takes very long until it's started.
I did a git-bisect and found out that this is the first bad commit: commit e9e2cdb412412326c4827fc78ba27f410d837e6e Author: Thomas Gleixner <tglx@linutronix.de> Date: Fri Feb 16 01:28:04 2007 -0800
[PATCH] clockevents: i386 drivers
Add clockevent drivers for i386: lapic (local) and PIT/HPET (global). Update the timer IRQ to call into the PIT/HPET driver's event handler and the lapic-timer IRQ to call into the lapic clockevent driver. The assignement of timer functionality is delegated to the core framework code and replaces the compile and runtime evalution in do_timer_interrupt_hook()
Use the clockevents broadcast support and implement the lapic_broadcast function for ACPI.
No changes to existing functionality.
So I tried to boot with nolapic on battery and with this option the kernel (and system) starts as it should. If you need more information, I will send it to you.
