Guru meditation when using RT kernel — at Initial Version
| Reported by: | Rainmaker | Owned by: | |

Description
When a host is running Debian Sid, and using the rt-kernel patchset, VirtualBox is unstable. Especially my Windows 2003 guest often crashes in a "guru meditation". Other guests, running Scientific Linux 6.1 (basically Redhat Enterprise Linux 6.1), do crash, but less often.
In dmesg on the host, a lot of these errors are visible, but the timing does not exactly match guru meditiations. Therefore, I'm unsure if these are the cause, a side effect, or harmless, but I'll mention them anyway :)
Full VBox.log is attached.
