&gt; Subject: [ale] Software RAID Problems
&gt;
&gt;
&gt; I recently purchased a Promise IDE controller and I am trying to set up
&gt; a 2 drive RAID set on it, but it's not cooperating.  I have tried to to
&gt; build the raid a few times and this is what I see, followed by a hard
&gt; lockup.
&gt;
&gt; Feb 29 20:05:31 shosta md0: max total readahead window set to 508k
&gt; Feb 29 20:05:31 shosta md0: 1 data-disks, max readahead per data-disk:
&gt; 508k
&gt; Feb 29 20:05:31 shosta raid1: device ide/host2/bus1/target0/lun0/part1
&gt; operational as mirror 1
&gt; Feb 29 20:05:31 shosta raid1: device ide/host2/bus0/target0/lun0/part1
&gt; operational as mirror 0
&gt; Feb 29 20:05:31 shosta raid1: raid set md0 not clean; reconstructing
&gt; mirrors

&gt; mirrors

&gt; Feb 29 20:06:35 shosta hde: dma timeout retry: error=0x40 {

&gt; Feb 29 20:06:45 shosta hde: irq timeout: status=0xd0 { Busy }
&gt; Feb 29 20:06:45 shosta
&gt; Feb 29 20:06:45 shosta PDC202XX: Primary channel reset.
&gt; Feb 29 20:06:45 shosta ide2: reset: success
&gt;
&gt; The ide2: reset is what is most likely causing the hard lockup, but I
&gt; have no idea what to do to fix this.  I have tried multiple drives and
&gt; different ribbon cables, and no luck.  Has anyone else seen this?
