Comment 17 for bug 1436319

Hi there,

Is there an update with this bug?

I am hitting it, or something very similar with 16.04 on EC2 with Xen EBS volumes.

32
root@ip-10-124-125-119:~# echo 64 > /sys/block/xvdc/queue/nr_requests
-bash: echo: write error: Invalid argument

I am not able to even set a queue size of below 128 now.
