[Bug 1180419] Re: Ringtail on Hyper-V causes BUG: scheduling while atomic
I've tested linux-image-generic:amd64 3.8.0.30.48 running on Windows
2012 and the BUG/backtrace has gone.
Brad:
Your comments may have been a bit overly automated as the tags in this bug already contained verification-done when you added your comment (so you in turn set verification-done). Although your comment didn't mention it, I've changed verification-needed-raring to verification-done-raring so hopefully the right thing will happen.

[ 23.921.954] BUG: scheduling while atomic: swapper/0/0x10000100
[ 168.973600] end request: I/O error, dev sda, sector 16786984
[ 168.973780] Buffer I/O error on device sda1, logical block 2098117
Similar messages repeat a few times, until it starts complaining about
an offline device. The CPU is showing pretty high activity.
Halt from command line works on this system.
It is only when a shut down command is issued from hyper-v
