Very odd indeed. I suggest you post the relevant information (like the
bootstrap log, output from `lspci -v', the contents of /proc/cpuinfo,
etc.) together with the description of the problem (so that the report is
self-contained) here and perhaps somebody will be able to diagnose it
properly. It could be some ACPI breakage.
