hda: dma_timer_expiry: dma status == 0x20
 

Hi,

I am encountering this message when I dmesg:

-------------------------------------------------------------------------------
hda: dma_timer_expiry: dma status == 0x20
hda: timeout waiting for DMA
hda: timeout waiting for DMA
hda: (__ide_dma_test_irq) called while not waiting
hda: status timeout: status=0xd0 { Busy }

hda: drive not ready for command
ide0: reset: success
--------------------------------------------------------------------------------

Should I be concerned about this? Is this a problem? I am running 2.4.20-13.8 from redhat8.

I am also running the system in Raid1. Thanks for your help.

BTW, my motherboard is ASUS P4B533

one of your drives is getting errors when running dma,
linux resets the drive, often turning dma off, which
takes a while, then continuing. if your drives are all
set dma, and you never see that error while running,
but just during boot, then don't worry about it. you
could probably set that drive to one speed slower, to
be safe. i've had several drives i had to do that with.
