I just re-tested using vb 4.1.12. The client is Ubuntu 11.10 32-bit, with updated guest additions and PAE/NX enabled. The host is Ubuntu 64-bit (i7 CPU). When hibernating the client, the error window appears saying ""A critical error has occurred while running the virtual machine and the machine execution has been stopped"" etc. VBox.log will be attached" defect closed other VirtualBox 4.1.12 obsolete hibernate Linux Linux
