2.4.47 bug - PnPBIOS GPFs and kernel panics

[Joseph Pingenot]

Hello.

Upon enabling PnPBIOS in the kernel, compiling, and rebooting into it,
  I get greeted with the following:
PnPBIOS: Found PnPBIOS installation structure at 0xc00f7d50

Another two error reports on the way, unrelated to this one.

Congratulations your PnP BIOS appears to be buggy. Can you send me the
output of dmidecode, also let me know if you used acpi

Can you try the latest -bk version?  I think there's some patches in
there that might fix the problem.
