Guru meditation when using RT kernel — at Version 1

Reported by: Rainmaker Owned by:
Component: host support Version: VirtualBox 4.1.4
Keywords: Cc:
Guest type: other Host type: Linux

Description (last modified by Frank Mehnert)

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.
