[Bug 1396889] Re: kexec reboot fails
The first bad commit is 8ab3820fd5b2896d66da7bb2a906bc382e63e7bc x86, kaslr: Return location from decompress_kernel which introduces KASLR. The problem only presents itself when CONFIG_RANDOMIZE_BASE=y. While this bug has been around in the kernel source for quite a time, it was dormant, as this option wasn't enabled in some previous Ubuntu kernel configurations. (This actually caused some headache during the bisection, as I needed to realize that I have to make sure this option is always enabled to get proper test results.) -- 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: 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

MegaBrutal, the issue you are reporting is an upstream one. Could you please report this problem to the appropriate mailing list by following the instructions _verbatim_ at https://wiki.ubuntu.com/Bugs/Upstream/kernel ? Please provide a direct URL to your e-mail to the mailing list once you have made it so that it may be tracked.

[Bug 1396889] Re: kexec reboot fails
** Description changed: After release upgrade to Utopic, when I reboot with kexec (simply with reboot command), my computer cold reboots after Starting new kernel (i.e. I need to get through the POST and GRUB), instead of the new kernel being loaded. Previously I didn't experience problems with Trusty. It matters which kernel I try to boot, while it doesn't matter what kernel I kexec from, and which version of kexec-tools I have. I can't boot 3.16.0-25, nor 3.18.0-031800rc6 from any installed kernels, while I can boot 3.13.0-39 from any kernels without any problems. I tried to downgrade kexec-tools from 1:2.0.7-1ubuntu2 (utopic) to 1:2.0.6-0ubuntu2.1 (trusty), but it made no difference. - I have a Lenovo Thinkpad T410. I didn't experience the same on my other + I have a Lenovo Thinkpad T400. I didn't experience the same on my other machines, so I suspect some hardware-dependent issue.

MegaBrutal, the next step is to fully commit bisect from kernel 3.13 to 3.16 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ? Please note, finding adjacent kernel versions is not fully commit bisecting. Thank you for your understanding.

[Bug 1396889] Re: kexec reboot fails
MegaBrutal, thank you for reporting this and helping make Ubuntu better. As per http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t400 an update to your BIOS is available (3.24). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, then please mark this report Status Confirmed. Thank you for your understanding. ** Tags added: bios-outdated-3.24 ** Changed in: linux (Ubuntu) Importance: Undecided = Low ** 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/1396889 Title: 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
