I turned on taskfile io on my last kernel, and had some stability
problems. This is ia32, all ide but with ide-scsi.
I experienced severe performance disruptions followed by what appeared to
be a system hang twice. Before that, I was recieving an "hdd: lost
interrupt" message every few hours, and the system felt sluggish. (The
ide-scsi device is hdc, not hdd.) I have not had these problems with a
kernel compiled without taskfile io.
Is this a known problem? I can provide more information if it would be
helpful.
I also got the following, which looks like what Nick Evgeniev reported May
24 (2.4.19-pre8 ide bugs). Andre said to him

As I had enabled taskfile IO, I figured I'd mention this:
