If you still have problems with ACPI mode, then open a bug report here: http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI and attach the output from dmesg -s64000 from the default and acpi=off boots. check that the driver to IRQ mapping in /proc/interrupts is the same in both cases. Look if there is a temperature reported under /proc/acpi/thermal_zone/*/temperature and see if perhaps your system is getting hot when it fails. Make a note if you can hear the fans turn on/off, and at what temperature. provide the output from acpidump in the bug report. thanks, -Len
