The kernel does not write any relevant logs to = disk when the lockups occur, making debugging difficult. I am open to suggestion= s on how to debug this problem, and about any kernel options I can apply to iden= tify the cause of the lockup. The kernel parameters for hardware watchdogs and hard lockup panic do not w= ork. Neither do sysrq keys. The lockup does not behave as a kernel panic - kexec= is not used, and neither does the caps light blink. Model: Yoga 9i 14ITL5 82BG Kernel: 5.18.4 --=20 You may reply to this email to add a comment.
