Re: Linux 2.4.21-rc3 : IDE pb on Alpha

[Willy Tarreau]

Hi again !

the system could boot without DMA. It displayed lots of messages, but it seems
to work :

------
After that, nothing special. I'm amazed by the number of "blk: queue..."
messages. This time, it only appears on SCSI, and not on IDE anymore.

So it seems as the IDE problem is in the ALI 1543 / DMA code. I have an old
K6/2 notebook somewhere with the same IDE controller, so I may retry on it.

I'm interested in any suggestion, of course ;-)
