Once in a while, a software bug in the kernel will cause a random reboot, so in order to help kernel developers to fix and troubleshoot the reboots, a kernel log need to be submitted to the developer for further analysis and hopefully lead to a bug fix.
Most Android kernels have "RAM Consoles" to save the necessary kernel logs immediately after reboot in the RAM. The users can then retrieve this RAM log on a subsequent reboot to submit to kernel developers. Here is a quick tour on how to do that.
- adb shell
- su
- cat /proc/last_kmsg > /sdcard/last_kmsg.txt
- exit
- exit
- adb pull /sdcard/last_kmsg.txt
- su
- cat /proc/last_kmsg > /sdcard/last_kmsg.txt
- exit
- exit
- adb pull /sdcard/last_kmsg.txt
File last_kmsg.txt will be located on your SD-card.
- go to /proc folder
- copy last_kmsg to /sdcard/
- rename last_kmsg to last_kmsg.txt
File last_kmsg.txt will be located on your SD-card.
The best method to share the last_kmsg.txt content is to upload it to pastebin.com and send a link to the developer.
