ATAPI DMA timeouts showing up in logs

Now that I've got the proper IDE driver in place (2.4.20rc4) and the master drive on the primary interface is running at a full ATA133, these have started showing up in the logs - 2 or 3 a day:
My guess is its the IDE command/DMA sequence bug that Khalid fixed in -ac. Some drives also take a very long time on retrying blocks and that might cause a timeout/reset too.
OK.
Interestingly enough, the drive wasn't being used at all during the timeframe when the messages show up - at least, not explictly. Perhaps some random process was polling the drive....
Alan, I tried 2.4.20rc4-ac1 but while the patch took, it wouldn't compile. I'll try again later and fwd where the error was. (I don't have access to that machine at the moment)

Those are ones CD-ROM's dont support
Ah, OK. Perhaps hdparm shouldn't try them then. :)
Thanks.

There have been quite a few posts to linux-kernel about IDE diagnostic messages that people are interpreting as fatal errors when they aren't, and I've noticed that Documentation/ide.txt hasn't been updated much for a long time - maybe it would be worth bringing it up to date?
Is the current maintainer Mark Lord or Marcin Dalecki? In the 2.5.x tree, it's had obsolete info removed, but it hasn't been brought up to date.
John.

In theory its Andre & I - it does want updating badly
