Re: SMART problems in 2.6.22

[Bruce Allen <ballen@gravity.phys.uwm.edu>]

Here is another similar report:

http://article.gmane.org/gmane.linux.utilities.smartmontools/4704/match=diamondmax

Again, this indicates that SMART is enabled.  But it's not clear what the 
kernel version here is.  The report indicates that the problem started 
with an FC7 kernel upgrade
