https://bugzilla.kernel.org/show_bug.cgi?id=202349 Chris Murphy (bugzilla@xxxxxxxxxxxxxxxxx) changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |bugzilla@xxxxxxxxxxxxxxxxx --- Comment #5 from Chris Murphy (bugzilla@xxxxxxxxxxxxxxxxx) --- My suggestion is enable sysrq, and then type out the trigger line in a shell in advance without pressing return; and then hit return once the hang happens. It almost certainly will get through to the kernel even if the command doesn't return until after the system recovers. It might be more reliable to do this over ssh than through the desktop environment's terminal. If you're running systemd, you can extract the full dmesg using 'journalctl -k > kernel.log' without systemd you may need to reboot with boot param log_buf_len=1M and issue 'dmesg -n 8'before reproducing. -- You are receiving this mail because: You are watching the assignee of the bug.
