I built the latest version which reports itself as 5.38 from cvs.

The results, as you suspected, were no different. 

The setup :

The system is setup with sda and sdb being partitioned as follows :
/dev/sda1   *           1         243     1951866   fd  Linux raid
autodetect
/dev/sda2             244        1459     9767520   fd  Linux raid
autodetect
/dev/sda3            1460        1824     2931862+  fd  Linux raid
autodetect
/dev/sda4            1825       19452   141596910    5  Extended
/dev/sda5            1825        7295    43945776   fd  Linux raid
autodetect
/dev/sda6            7296       19452    97651071   fd  Linux raid
autodetect


raid1 mirrors are then setup between the corresponding partitions on the
two disks.

The results :

using either 5.37 or 5.38, issuing a smartctl -t long on either one of
the disk devices allows filesystem access at full speed, and issuing a
smartctl -X on the disk returns inside a second. All is well:

time dd if=/dev/zero of=file bs=1k count=1024
1024+0 records in
1024+0 records out
1048576 bytes (1.0 MB) copied, 0.00488519 seconds, 215 MB/s


Starting an extended self-test on *both* disks, however, and filesystem
access is *extremely* slow, which may be why the violations are
happening, although I didn't leave it running long enough to impact the
box:
 time dd if=/dev/zero of=file bs=1k count=1024
1024+0 records in
1024+0 records out
1048576 bytes (1.0 MB) copied, 0.00505913 seconds, 207 MB/s

real    0m9.107s
user    0m0.000s
sys     0m0.004s

Now, I'm asking the guy who runs the system as to when I can test the
smartd, but I'm guessing from this that the results will be exactly the
same.

Comments?

Cheers,
Eamonn
