Hi all,
I have a machine running an array of 8 WD SATA drives, kernel 2.6.11.12
patched with libata-devel to get smart working. I'm consistently getting
these errors:

Does anyone have a clue what's going on here? I remember reading
somewhere that the libata patch to get smart working was not "safe"
because it did not make sure a command was already executing. Could that
be what's going on? I'm using smart to log the temps of the drives every
5 minutes.
Any ideas would be appreciated.
thanks,
/Patrik
