I don‘t really have enough expertise, but my uneducated guess would be that there is a problem with memory management in the guest UML. Could it be related to the following? http://www.mail-archive.com/user-mode-linux-user@lists.sourceforge.net/msg04597.html
I‘d like to do some more testing. Could you post a minimal kernel configuration which still provokes the error? -- Best Regards, Leonid Chaichenets. ------------------------------------------------------------------------------ The NEW KODAK i700 Series Scanners deliver under ANY circumstances!
