Just wanted to add that upgrading my kernel to a newer version fixed the
problem for me, too.

Host: 2x E5-2620V2, Ubuntu 14.04 LTS
Guest: 24 virtual cores, Windows Server 2008 R2

Before fix:
sudo uname -a
Linux x.contabo.net 3.13.0-44-generic #73-Ubuntu SMP Tue Dec 16 00:22:43 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
Bluescreen stop 0x0000005c every few hours

After fix:
sudo uname -a
Linux x.contabo.net 3.16.0-23-generic #31-Ubuntu SMP Tue Oct 21 17:56:17 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
No Bluescreens or other crashes since 7 days under full load

Upgraded with this tutorial http://askubuntu.com/questions/541775/how-
can-i-install-ubuntu-14-10s-kernel-in-ubuntu-14-04-lts
