Hi, Is there any possibility of getting tickless mode working on my system? I am using kernel 2.6.23, and using the latest BIOS. This is on an Dell Inspiron 1501.
I get hundreds of "extra timer interrupt" wakeups according to powertop. With earlier kernels, I notice that broken lapic related freezes go away once the system had booted (required tapping keys to get it there though). So, would it be possible to use some other clocksource until the boot process was finished and then switch to lapic mode? Or am I at Dell's mercy here? I am happy to test patches and help to debug should anyone have any code/ideas on how to go about this, but my kernel-fu is weak. I see the following in my dmesg: ACPI: RTC can wake from S4 Time: hpet clocksource has been installed. Clockevents: could not switch to one-shot mode:<6>Clockevents: could not switch to one-shot mode: lapic is not functional. Could not switch to high resolution mode on CPU 1 lapic is not functional. Could not switch to high resolution mode on CPU 0 Thanks, LL - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
