Description Ștefan Talpalaru 2007-10-14 11:42:10 UTC 
Most recent kernel where this bug did not occur: 2.6.22
Problem Description:
the controller gets assigned a different IRQ and the following message appears:
ata1: COMRESET failed (errno=880)
Here's the dmesg for a vanilla 2.6.23: http://pastebin.ca/736600 - line 70
and a dmesg from 2.6.22-ck1: http://pastebin.ca/736649 - line 199
Notice how the IRQ assigned to ata1 and ata2 was 18 and now is 17.

The patch is working. Thanks!
Comment 5 Tejun Heo 2007-10-18 19:24:15 UTC 
Alright, patch pending.  Resolving as FIXED.  I'll push the patch to -stable so that it will appear in 2.6.23.x once the patch is upstream.  Thanks.
