My system was running fine till I experienced an abnormal response where the whole system legitimately froze and keyboard won’t respond except the trackpad and movable cursor. I thought TTY was my last option yet keystrokes to enter didn’t happen unfortunately. I ended up forced shutdown holding power key till it booted fine. Please note I simultaneously switched between X11 and Wayland to ensure it’s not bug related to either of the sessions. My hardware is AMD Ryzen 6850U with AMD Radeons Graphics. Plasma version 6.2.1, KDE Frameworks: 6.7.0 and QT version 6.7.3 I have attached necessary logs along with link for the bug demo.

Sounds a bit like https://bugs.kde.org/show_bug.cgi?id=493277, see also the "See Also"s there.

For me it doesn't look like a duplicate of bug 493277, rather a bug in kernel bluetooth or one of its call sites: Oct 18 03:00:11 SUSE-Linux kernel: Oops: general protection fault, probably for non-canonical address 0xdead000000000108: 0000 [#1] PREEMPT SMP NOPTI Oct 18 03:00:11 SUSE-Linux kernel: CPU: 2 UID: 0 PID: 17451 Comm: kworker/2:0 Not tainted 6.11.3-1-default #1 openSUSE Tumbleweed 1400000003000000474e550081ddd499447a1db8 Oct 18 03:00:11 SUSE-Linux kernel: Hardware name: LENOVO 21CFS00W00/21CFS00W00, BIOS R23ET78W (1.54 ) 08/05/2024 Oct 18 03:00:11 SUSE-Linux kernel: Workqueue: usb_hub_wq hub_event [usbcore] Oct 18 03:00:11 SUSE-Linux kernel: RIP: 0010:hci_unregister_dev+0x4c/0x1e0 [bluetooth] ...
