[Bug 1480921] Re: kernel panic on bootup
Did tests, with following result: - 4.2.0-rc5 upstream: works (although wifi driver missing but that's unrelated) - 3.19.0-25-generic (from 'linux-generic-lts-vivid'): works - 3.16.0-45-generic (from 'linux-generic-lts-utopic'): works 3.13.0-57 and earlier: works (tested: 57, 55, 54, and various lower ones) 3.13.0-58, 3.13.0-59, 3.13.0-61, kernel panic (see comment #3 for screenshot) so it appears the regression was introduced in 3.13.0-58, and later kernel series have no issues. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1480921 Title: kernel panic on bootup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1480921/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Screenshot is in comment #3.

Also, can you capture and post a screen shot of the panic? ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1480921 Title: kernel panic on bootup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1480921/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.2 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

Due to nature of the issue, I cannot run apport-collect. The best I can do is a (literal...) screenshot ** Attachment added: "screenshot" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1480921/+attachment/4438378/+files/2015-08-03%2017.23.35.jpg ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1480921 Title: kernel panic on bootup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1480921/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
