Trapping Errant DMA Disk Ops
log entry: kernel: hda: dma_timer_expiry: dma status == 0x61
They may be due to a failing disk, MB, or cable problems but they can stop the
system in its tracks. If the disk be mounted or otherwize being accessed, big
red switch time. Otherwize, that wonderful click-clack of WD disks is the
warning. Smartmon does not issue anything in time, it seems.
How might one configure smartmon to trap this "sooner". What I would want is
to kill anything accessing the disk and then stop itself from doing so as
well since smartmon is the likely accessing process. Try to save system from
paralasis!
