Comment 1 Prarit Bhargava 2007-05-01 16:04:42 UTC 
Actually the errors do not occur on the _mount_.  They occur when the CD tray is
opened and closed.

Comment 2 Prarit Bhargava 2007-05-01 16:05:52 UTC 
Adding Conke & Bhavana as they have had experience with this chipset.

Conke, I just found this issue this AM -- any ideas?

Comment 4 Prarit Bhargava 2007-05-07 15:49:44 UTC 
Backport of http://lkml.org/lkml/2007/4/11/356 resolves this issue.

Note that board_ahci_sb600 = 2 because of missing patchsets for other HW.
