Thanks for the report. I'm sorry but this looks like a single-bit error. From
the oops, it looks like the kernel tried to dereference address 0xb05cad1c
while the correct address would be f05cad1c (as you can see, lots of addresses
in this range are in registers so that's probably where kernel has it's data on
your machine). So I'd blame either cosmic rays or faulty HW. Maybe try running
memtest, or try replacing memory if it repeats. I'll close the bug as
invalid...
