Public bug reported: This issue impacts Ubuntu 12.04.
Whenever a device is unregistered in vmbus_device_unregister (drivers/hv/vmbus_drv.c), the device name in the log message may contain garbage as the memory has already been freed by the time pr_info is called. Log example: [ 3149.170475] hv_vmbus: child device àõsèè0_5 unregistered By logging the message just before calling device_unregister, the correct device name is printed: [ 3145.034652] hv_vmbus: child device vmbus_0_5 unregistered This issue has been resolved with the upstream patch: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/hv/vmbus_drv.c?id=84672369ffb98a51d4ddf74c20a23636da3ad615 ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1417313 Title: [Hyper-V] vmbus: incorrect device name is printed when child device is unregistered To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1417313/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
