OK, it looks like this is due to an botched switch from IDE to libata
drivers on MIPS.  The qemu emulated HD controller is now being handled
by the ide-generic driver whereas it should have been switched from piix
to ata_piix, and ide-generic triggers this panic for reasons I don't
fully understand.

This will get fixed, but not immediately.
