orion kernel: =======================
Is there a solution, or is this still a kernel bug???
This can happen for countless different reasons. This one appears to be
acpi-related, which generally means that the kernel is having difficulty with
how the BIOS is describing the hardware. A BIOS update might help, but if not,
we need to know a lot more about the hardware. Booting with acpi=off might also
fix it, but with a modern system that cripples an awful lot of functionality.
