>This box didn't boot on 2.6.18-rc2. >(The last kernel I tested which worked (at least until it broke for >other reasons...) was 2.6.17-rc2.) it would be great if you can confirm that 2.6.17.stable works properly. Then enable CONFIG_ACPI_DEBUG=y on 2.6.17.stable and you should see the "BIOS reported wrong ACPI id" message like below. That message was enabled by commit 0eace for bugzilla 5452 at 2.6.17-git9. The AE_NOT_EXIST part, I think, may be new. Might need acpidump output in a bugzilla to figure it out. >BIOS reported wrong ACPI idfor the processor >ACPI Exception (evxface-0545): AE_NOT_EXIST, Removing notify >handler [20060707] >BIOS reported wrong ACPI idfor the processor >ACPI Exception (evxface-0545): AE_NOT_EXIST, Removing notify >handler [20060707] >BIOS reported wrong ACPI idfor the processor >ACPI Exception (evxface-0545): AE_NOT_EXIST, Removing notify >handler [20060707] >BIOS reported wrong ACPI idfor the processor >ACPI Exception (evxface-0545): AE_NOT_EXIST, Removing notify >handler [20060707] Unclear if the hang is actually related to ACPI.
