When booting my system it sometime hangs right after giving me the message Edge set to Level Trigger. but most times it works fine. Is this a known bug ? possibly a buggy ACPI implementation ?
I have included the ACPI portion of a successful boot below. If you want/need more information just ask.

Yes, I'd like to see if the complete dmesg includes this line:
Local APIC disabled by BIOS -- reenabling.

Yes, the problem is known, but the solution is not.

We've seen this problem go away many times with a BIOS upgrade, are you running the latest?

There is also a workaround here to temporarily disable the APIC timer:
http://bugme.osdl.org/show_bug.cgi?id=1269

Perhaps you can update that bug report to say if the workaround helps your system or not.

thanks,
