Looks like it died inside the machine's BIOS.

Please try reverting the three pnp patches:

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.0-test9/2.6.0-test9-mm4/broken-out/pnp-fix-3.patch
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.0-test9/2.6.0-test9-mm4/broken-out/pnp-fix-2.patch
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.0-test9/2.6.0-test9-mm4/broken-out/pnp-fix-1.patch

and let us know?

Other things to do would be:

- Add `initcall_debug' to the kernel boot command line, look up the final
  initcall address in System.map

- Disable pnpbios in kernel config

- Upgrade the bios

Thanks.
