I actually had a freeze on my system just now. This after
having worked all day. I am on the committed patch on the
back-end. Just rewinding slightly on the front-end,
followed by a pause/play fixed it.<br>

Did you also have a case when your backend took several seconds to
write 64kB of data?<br>
Indeed my /sys/block/sdX/device/queue_depth is set to 1. <br>
$ dmesg | grep -i ncq<br>

I'll look at the bios settings next but I wanted to understand if
you had the same symptoms.<br>
