Linux enables the Local APIC even on uni-processors systems so that it can use the LOCal APIC timer. This policy causes a significant population of laptops to freeze when booted with ACPI enabled. Curiously, we've seen this failure go away on some laptops after a BIOS upgrade -- so you shoul verify that you're running the latest BIOS for your system. Perhaps you could try the test patch here http://bugzilla.kernel.org/show_bug.cgi?id=2044 and add a comment to the bug report on if it makes any difference or not. > > > I escaped from CVS in 1994, underwent several years of therapy, and > > haven't used it since.
