On the linux 3.5 kernel series it got introduced with 3.5.7.1 upstream patch. 3.5.0-19 doesn't include that one. With 3.5.0-20 and 3.5.0-21 this patch got included. 3.5.7.1 includes 270 new patches with 2 efi- releated ones. Those seem to me sane so I still don't know which patch introduced this regression.
The linux 3.4 kernel series still seem to be fine. Only linux 3.6 and newer kernel version introduced this bug which got backported with 3.5.7.1 to the 3.5 kernel series. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1093617 Title: Kernel 3.5.0-21 will not shutdown on uefi booted machines To manage notifications about this bug go to: https://bugs.launchpad.net/linuxmint/+bug/1093617/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
