kernel 2.6.9rc2+bk hangs at: ACPI: IRQ9 SCI: Level Trigger.

kernel 2.6.9rc2+bk hangs at: ACPI: IRQ9 SCI: Level Trigger.

[Arkadiusz Miskiewicz]

My kernel (2.6.9rc2+cset-20040926_0006) hangs at:
Enabling unmasked SIMD FPU exception support... done.
Checking 'hlt' instruction... OK.
ACPI: IRQ9 SCI: Level Trigger.

Previous working kernel running here was 2.6.9rc2+20040914_1622.

I've tried options:
acpi=off
noapic
nolapic
acpi=off noapic nolapic
but no change - hangs with each these options, sysrq is not working.

Ideas welcome.

It's MaxData Mbook 1000T notebook with athlon mobile cpu.

More information.

This is unrelated to ACPI since kernel compiled without ACPI also hangs at:
,,Checking 'hlt' instruction... OK.''.

Something else is broken. Two other people confirmed the problem for me.

Compiled vanilla version and... it works.

I was using ck patchset and tracked this problem to single patch:
http://ck.kolivas.org/patches/2.6/2.6.9/2.6.9-rc2/2.6.9-rc2-ck2/patches/9000-SuSE-117-writeback-lat.patch

This is interesting... few cond_resched() added and such problem arrived.

Anyway problem solved.
