Hi, I have this nagging and frustrating boot freeze i often face on my Deepin OS boot ... Deepin OS i think uses 'journalctl' to record logs on its system.
'journalctl' however seems to record boot logs ONLY for successful boots ... boot logs for instances of boot freezes/hangs that are issued with a ... 'Ctrl+Alt+Del' ... key combination or the ... Magic Sysrq 'b' ... key combination to get out of the frozen/hung machine state are just not aved in the 'journalctl' log ... Is there any option using Magic Sysrq that will enable me to record the failed/frozen/hung boot information to a file for troubleshooting before i reboot the system using the option 'b' ? If not ... Isn't it a good idea to have such an option added to Magic Sysrq options, that can save/record the boot/system logs upto that point, until just before we restart the machines ? It would really help to have such an option ... an option to record and save the machine state(logs) before we reboot the system using the 'b' option of Magic Sysrq !!! thanks for looking
