Subject: hpet on nforce4/MCP51 in asus a6t
Date: Sun, 3 Feb 2008 19:33:57 +0100 (CET) [thread overview]
Message-ID: <19861822.1202063637753.JavaMail.root@ps23> (raw)
Hello,
I have a asus a6t with nforce4/MCP51 chipset. I pass to kernel 2.6.24
32 bit the options acpi_use_timer_override and hpet=force, in this way
and the timer IRQ ends up routed as IO-APIC-edge instead of XT-PIC.
With acpi_use_timer_override I just get:
TIMER: vector=0x30 apic1=0 pin1=2 apic2=-1 pin2=-1
and it works through the IO-APIC.
Instead the hpet is disabled and I just get :
Time: acpi_pm clocksource has been installed.
Clocksource tsc unstable (delta = -85010975 ns)
Is possible to have hpet working also with if the BIOS doesn't support
it ?
I wish to be personally CC'ed the answers/comments posted to the list
in response to my posting.
Cecco
