Here is an excerpt of the errors:
info task rs main q reg 1162 blocked for more than 120 seconds not tainted
This is a very inconvenient feature and I think I've nailed it. From Microsoft's site they have details on adding bits to your install that add functionality and (hopefully) will help avoid this issue.
The Microsoft page is here: https://technet.microsoft.com/en-us/windows-server-docs/compute/hyper-v/supported-ubuntu-virtual-machines-on-hyper-v?f=255&MSPPError=-2147217396
And the guts of it is to do the following (with 16.04):
- # apt-get update
- # apt-get install linux-virtual-lts-xenial
- # apt-get install linux-tools-virtual-lts-xenial linux-cloud-tools-virtual-lts-xenial
The error was something like Kernel not tainted or similar. So far it's working.
Update 2016-12-22
It stopped working. Super annoying. Have tried from this site: https://www.blackmoreops.com/2014/09/22/linux-kernel-panic-issue-fix-hung_task_timeout_secs-blocked-120-seconds-problem/
See how that goes.
Have also done the stuff on this site: https://oitibs.com/hyper-v-lis-on-ubuntu-16/
Will see how that goes.
