That's odd. I'll have to forward this to the keyboard/mouse team;
it doesn't sound directly related to ACPI. Though...
OK, here is the ACPI part of the boot messages:
Jul 4 21:41:45 s11 acpica: [ID 972481 kern.warning] WARNING: AcpiOsWritePort:
cf8 32 not permitted
Jul 4 21:41:45 s11 acpica: [ID 815887 kern.notice] ACPI-0519: *** Error:
Jul 4 21:41:45 s11 acpica: [ID 441208 kern.notice] Handler for [SystemIO] returned AE_ERROR
The system ACPI BIOS is attempting to access PCI configuration space
directly rather than using the correct PCI Config space operation regions.
This is unsafe - directly accessing config space like this is non-atomic.
The OSL implementation blocks these accesses.
