Unfortunately, it has happened again, with speeds at near zero.

It rebuilt fine in single user mode, with speeds usually around
50MB/sec. But after exiting single user mode, and allowing MythTV and
other programs to start, within 30 minutes I had the problem again.
Basically a hung filesystem. I couldn't even "cat /proc/mdstat", that
just hung. Lots of hung task warnings in dmesg.
Because Phil suggested that fsync calls might cause stalls, I commented
out the fsync in MythTV. I'll run with that for awhile, and see how
things work out. So far it isn't adversely affecting MythTV.
Thanks!

Have you set the io scheduler to deadline on all members of the array? That's
kind of "job one" on older kernels.

Plus I disable the on-drive queuing (NCQ) during startup, right now
I don't have benchmarks to show the difference. This on a six by 1TB
drive RAID6 array I built over a year ago on Slackware64-13.37:
# cat /etc/rc.d/rc.local
...
# turn off NCQ on the RAID drives by adjusting queue depth to 1
n=1
echo "rc.local: Disable RAID drives' NCQ"
for d in a b c d e f
do
echo " set NCQ depth to $n on sd${d}"
echo $n > /sys/block/sd${d}/device/queue_depth
done
...
Maybe you could try that? See if it makes a difference. My drives
are Seagate.
Grant.

Does disabling NCQ improve performance?
The suggestion to use kernel 3.4.6 has been working quite well so far,
hopefully that fixes the problem. I'll know for sure in a few more days...

We are not out of the woods yet, but we know the direction and have

I suspect you are being hit by same bug I was -- delayed stripes never
got processed. If you get into the state where the rebuild isn't
progressing, and you find that increasing the size of the stripe cache
allows the rebuild to proceed (but the filesystem stays wedged), then
that cinches it.
If you can, upgrade to the latest 3.4 stable kernel (3.4.6 right now).
As far as I can see, the latest 3.2 stable does not contain the delayed
stripe fix.
After applying those fixes to my kernel, my MythTV setup over a 5 disk
RAID5 has been pretty solid, where before I was getting lockups every
few days. It still seems to be getting slower over time, but I've not
looked into it yet as it is not as catastrophic as the wedging.
HTH,
Dave

And I was looking at the wrong version; 3.2.24 does indeed have the fix.

No, that was the one I looked at. It is commit
