Thanks for your advice PearZoo, it did not help. I found the equivalent module "asus_laptop" which handels the acpi-related stuff, and blacklisted it. furthermore, I tried the boot option "acpi=off", both no success. (total freeze at VM start)
With the (host) boot options "noapic nolapic" I can (just one time) start the 64-bit guest VM , which immediately gets a kernel panic (error message). When I give it another try, total freeze. -- starting virtual machine in virtualbox-ose freezes system https://bugs.launchpad.net/bugs/347487 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
