[olug] RE: HDC: Lost Interrupt Error

[Brian Wiese]

Perhaps youre hard drive is very old and doesnt support DMA?  Adam
mentioned using "hdparm -d 1 /dev/hda" I believe.  Hrmm... if this seems
to have solved it, no errors for days, thats good to know.

|Nah, I don't think it is an error with XMMS, my
