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. Ben. -- Ben Hutchings Once a job is fouled up, anything done to improve it makes it worse.
