Hi all, I use the form I've been requested to use to report the kernel bug below.
[1.] One line summary of the problem: When I reboot with kexec, 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 booted instantly. [2.] Full description of the problem/report: To reproduce, install kexec-tools, set it up so that it shall try to reboot the actual mainline kernel. Then issue a kexec reboot (if kexec installed a "reboot" hook script, just issue "reboot"). You should see a "Starting new kernel" message before the reported problem presents itself. I have a Lenovo Thinkpad T400. I didn't experience the same on my other machines, so I suspect some hardware-dependent issue. The problem is introduced by KASLR and is present on kernels compiled with CONFIG_RANDOMIZE_BASE. [3.] Keywords (i.e., modules, networking, kernel): [4.] Kernel version (from /proc/version): Linux version 3.18.0-031800rc7-generic (apw@gomeisa) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #201411302035 SMP Mon Dec 1 01:36:38 UTC 2014 [5.] Output of Oops.. message (if applicable) with symbolic information resolved (see Documentation/oops-tracing.txt) N/A (I have no Oops message, or at least it's not visible). [6.] A small shell script or example program which triggers the problem (if possible) See #2 for reproduce instructions, no shell script is required. [7.] Environment $ lsb_release -rd Description: Ubuntu 14.10 Release: 14.10 [7.1.] Software (add the output of the ver_linux script here) If some fields are empty or look unusual you may have an old version. Compare to the current minimal requirements in Documentation/Changes.

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1396889 With kernel bisection, I've found, the first bad commit is 8ab3820fd5b2896d66da7bb2a906bc382e63e7bc x86, kaslr: Return location from decompress_kernel which introduces KASLR. http://lkml.kernel.org/r/1381450698-28710-3-git-send-email-keesc...@chromium.org The problem only presents itself when CONFIG_RANDOMIZE_BASE=y. For workaround, there is a "nokaslr" kernel parameter to disable the feature, even if the kernel was compiled with CONFIG_RANDOMIZE_BASE. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
