Re: Panic after enabling PNPBIOS and pcm device

From: Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>

    It looks like it crashed from *within* a BIOS call.  These kinds
    of crashes are extremely difficult to track down because, more often
    then not, they occur due to BIOS bugs rather then due to kernel bugs.
