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. Bjorn
