Can you recreate this with the latest 2.6.40.x F15 kernel and without the vbox modules loaded?
(In reply to comment #1) > Can you recreate this with the latest 2.6.40.x F15 kernel and without the vbox > modules loaded? I am running fedora 15 on two virtual machines (both on a windows vista host) and on two of my servers. In general I keep them all pretty much up to date. For two months or more I have not experienced any of the crashes/bugs that were occurring when Fedora 15 first came out and things are a lot more stable. As far as I can tell from my records this kernel event only happened on a virtual machine so it may well have been due to the interaction between the vbox modules and the kernel at that time. As well as the fedora 15 programs, the Virtual box programs I am now using are also now a few more versions advanced than they were at the time of this bug. I filed this bug in response to the abrt message which asks if you want to report the event to the kernel developers. It was just something that happened while I was working and I do not think I could reproduce it easily or at all. However I do hope the above is of some help to you.
Thanks for letting us know. We'll close this out as WORKSFORME since it is difficult to recreate and we haven't really seen many reports of it.
