Len, just to confirm that the mentioned patch fixes my boot hang (HP Omnibook 6100, newest BIOS) with kernel-2.6.6. With acpi enabled it needed "nolacpi" to come up. It would always just stop after the lines: ACPI: Subsystem revision 20040326 ACPI: IRQ9 SCI: Edge set to Level Trigger. ACPI-0179: *** Warning: The ACPI AML in your computer contains errors, please nag the manufacturer to correct it. ACPI-0182: *** Warning: Allowing relaxed access to fields; turn on CONFIG_ACPI_DEBUG for details. Apparently the SuSE supplied 2.6.4-54.3 has that (or a similar) fix in it, as the notebook boots fine with that. Only remaining problem now is that I have the "gut feeling" that I am missing some mouse events with acpi enabled. That maybe XFree related.
