ata1: illegal qc_active transition (3fffffff->fffffffe)
I'm getting this about once every 3 days. When this happens, the affected
partition is remounted read-only (per my file system error options).
I am not certain if this is telling me I have a hardware error,
incompatibility, or if there's a design problem with the driver.
