[Bug 49265] Re: Intel 440BX: 'hda: I/O error'

[Pascal de Bruijn]

That could very well be the case:

pmjdebruijn at tsunami:~$ sudo hdparm /dev/hda

/dev/hda:
 multcount    =  0 (off)
 IO_support   =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  0 (off)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 geometry     = 65535/16/63, sectors = 78165361, start = 0
pmjdebruijn at tsunami:~$

My healty system differs quite a bit:
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)

So yes, I could possibly have been bitten by that bug.

But, could the disabled DMA not by the results of those IDE errors.
Instead of the other way around? It seems logical that when multiple IDE
errors occur DMA gets disabled to rule out a faulty DMA controller.
