Hummm, somehow we are executing data, not code:

00000000  8c 39 00 00 01 82 44 45  4c 4c 20 20 50 45 5f 53  |.9....DELL  PE_S|

That isn't a valid instruction. :(

Also, your eip value is not anything that would be normal.

Actually, your eip value looks like a pointer into the BIOS (0xf000:bf6a).

I bet something in your BIOS had a buffer overrun and trashed the stack or
some such.  Or it overran an I/O buffer which trashed the return stack of
the userland process somehow.
