[Bug 1396889] Re: [Lenovo ThinkPad T400] kexec reboot fails
Is there anything I can do to get the patch actually backported? Can I somehow backport it myself or something? Even with the latest Utopic kernel which was published few days ago, I still don't have a kexec-able kernel. I can imagine the Vivid release will happen earlier than I'll get a patched kernel in Utopic. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1396889 Title: [Lenovo ThinkPad T400] kexec reboot fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1396889/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1396889] Re: [Lenovo ThinkPad T400] kexec reboot fails
MegaBrutal, the next step is to fully reverse commit bisect from kernel 3.18-rc7 to 3.19-rc7 in order to identify the last bad commit, followed immediately by the first good one. Once this commit has been identified, then it may be reviewed as a candidate for backporting into your release. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ? Please note, finding adjacent kernel versions is not fully commit bisecting.

[Bug 1396889] Re: [Lenovo ThinkPad T400] kexec reboot fails
I've tested the issue with mainline kernel v3.19-rc7-vivid, and it works now! However, the actual Ubuntu kernel, 3.16.0-30-generic, still has the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1396889 Title: [Lenovo ThinkPad T400] kexec reboot fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1396889/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Please try the patch mentioned here: https://lkml.org/lkml/2014/12/1/790 If it works, it would be nice to tell the authors to get it included in the mainline kernel. I've already told them, but one man is probably not enough. (I'm not sure if it's included already, and currently I have no time to test.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1396889 Title: [Lenovo ThinkPad T400] kexec reboot fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1396889/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1396889] Re: [Lenovo ThinkPad T400] kexec reboot fails
I'm on a virtual machine and experiencing the same thing. The problem seems to be covered pretty well in pages mentioned in #8. My problem in more detail is trying to kexec the 3.16 kernel provided by linux-generic-lts-utopic in trusty (from original 3.13 kernel, to allow "normal" kernel updates on DigitalOcean). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1396889 Title: [Lenovo ThinkPad T400] kexec reboot fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1396889/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
