Comment 1 Josh Boyer 2011-09-26 18:23:52 UTC

Can you recreate this issue on the latest 2.6.40.x F15 kernel?  If so, what is going on at the time of the error?

Comment 2 Dave Jones 2011-10-06 22:13:22 UTC

also, please try reproducing without the virtualbox modules loaded.
They've been known to cause a number of problems just like this.

Comment 3 Frank Mehnert 2011-10-12 14:57:12 UTC

Please try out the test options one by one. Also, which version of VirtualBox are you using?
