Thanks very much for the report.  This sounds like it could be a
PNPACPI issue, which I am very interested in fixing.

Can you please turn on CONFIG_PNP_DEBUG in your .config and collect
the complete dmesg log with and without "pnpacpi=off"?

I do have an "lspnp" that works with PNPACPI here:
  http://kernel.org/pub/linux/kernel/people/helgaas/pnputils-0.1.tar.bz2
but it's not widely used.  The debug information from the config
option above is usually more useful.
