Have the same issues with every kernel I've tried in the Fedora 29 repos. Machine freezes, usually multiple times per day. Mouse cursor moves, but won't respond to clicks. No other input works. Num lock light on keyboard is frozen (cant toggle it on/off from num lock key). Cannot switch to virtual terminals, cannot sysreq+reisub, nothing. No response via icmp, no other services respond. Seems to happen most frequently waking from sleep, but that might just be my impression. What I have tried: Set powersupply to "Typical Current Idle" in bios Disabled c-state control in bios Compiled kernel with RCU_NOCB_CPU (it was already config in fedora kernels) Added rcu_nocbs=0-15 to kernel boot Added idle=nomwait to kernel boot Added processor.max_cstate=5 (I realize some of this is redundant, I was grasping at straws) For reference, heres is my kernel boot line:BOOT_IMAGE=/vmlinuz-4.20.5-jmd root=/dev/mapper/fedora_localhost--live-root ro resume=/dev/mapper/fedora_localhost--live-swap rd.lvm.lv=fedora_localhost-live/root rd.lvm.lv=fedora_localhost-live/swap rhgb quiet LANG=en_US.UTF-8 idle=nomwait processor.max_cstate=5 rcu_nocbs=0-15 Attached is journalctl output covering the time period, and a little further back. -- You are receiving this mail because: You are watching the assignee of the bug. ----- End forwarded message ----- -- Regards/Gruss, Boris.
