Hello!

We have an HPT302 IDE controller with two channels - primary/secondary


linux-2.4.22 IDE driver recognizes this controller, but fails to 
properly work with two channels simultaneously.

Full dmesg included

Workaround for this problem - either use highpoint scsi driver
(http://www.highpoint-tech.com/hpt302-opensource-v1.1.tgz)
 or move all hard disks to one channel (after that  linux driver works 
great)
