>Release:        RELENG_6_3
>Organization:
n.a.
>Environment:
Freebsd 6.3 i386 (RELENG_6_3 update of 25/02)
(will post uname -a as I get back to the machine)
>Description:
- Upgraded6_3 RELEASE to RELENG_6_3 last night (25/02/2008)
- After reboot, second SATA spawned folowing errors :

ad6: FAILURE READ_DMA TIMOUT
CANNOT READ BLK: xxxxx
UNEXPECTED SOFTWARE UPDATE INCONSISTENCY

--> Since this disk has the /home partition on it I'm unable to boot.

Note that :
-----------

- manual fsck does NOT fix it, even with fsck -y to remove things.

- there are 2 identical drives in the machine, both Seagate Baracuda ST3160811AS
  Only the 2nd one fails, which unfortunately has the /home partition on it.



>How-To-Repeat:
- reboot and wait until boot-process reaches fstab parsing, then it fails with the error above.
>Fix:
