Description Guilherme Amadio 2014-03-10 21:27:17 UTC 
At boot, Seagate Momentus SpinPoint M8 drives (ST1000LM024 HN-M101MBB) show the following errors:

[    2.555905] ata2.00: failed to enable AA (error_mask=0x1)
[    2.568482] ata2.00: failed to enable AA (error_mask=0x1)

The original bug reports for this problem are at https://bugzilla.redhat.com/show_bug.cgi?id=907193 and 
https://bugzilla.redhat.com/show_bug.cgi?id=1073901

Several firmwares are affected. Firmwares 2AR10001 and 2BA30001 have been patched for, while a newly reported firmware, 2AR30001 has not:

If this problem is reported for more firmwares, we should consider patching for all of them.

Best,

The user who reported (in the original bug) firmware 2AR30001 as being affected actually had firmware 2BA30001, which is already patched.
