I think this is a bug in the Ubuntu qemu-kvm package, not in the kernel. (How to change the package that this bug is reported against?)
I tried compiling the Ubuntu qemu-kvm package without any patches (except define_AT_EMPTY_PATH.patch which is required in order for the package to compile). However the bug was still reproducible. So the bug is not caused by any Ubuntu patch. I compiled qemu from git tag 'v1.0' => bug was reproducible. I compiled qemu from git HEAD (currently da12872a097) => bug was NOT reproducible. This proves that some commit in that range fixes the problem, but I haven't yet worked out which one it is. ** Summary changed: - ADFS partition checking code hangs on empty virtio disk + QEMU 1.0 causing hang when adding a virtio disk ** Tags removed: kernel-bug-exists-upstream kernel-da-key precise -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/931371 Title: QEMU 1.0 causing hang when adding a virtio disk To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/931371/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
