Hi:

The laptop in $SUBJECT freezes at boot time, at random points sometimes 
after

[FIRMWARE BUG] ACPI(PEGP) defines _DOD but not _DOS

But in other ocassions, just after udev attempts to mount filesystems.

Using the following boot options make the system boot and work somewhat 
stable.

(these are single options, not combined)

- acpi=noirq

- pci=noacpi --> with this option I get warnings telling me to try 
"usepirqmask..."

- nox2apic

- intremap=off

This is a very recent sandy bridge system, the only clues I get from the 
log is:

"Not all IO-APIC's listed under remapping hardware
x2apic not enabled, IRQ remapping init failed"

The system is running with the most current BIOS (released 3 days ago)

If someone has an idea what other info I can provide to track down this 
issue just let me to know.

ps: I tried with acpi debug boot options, but do not yield much info..

Thanks in advance.
