http://bugzilla.opensuse.org/show_bug.cgi?id=1204705 Bug ID: 1204705 Summary: KDE Plasma fails to start with Kernel 6.0.3 Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: 64bit OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: postix@posteo.eu QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Since updating from kernel 6.0.2 to 6.0.3 on openSUSE TW, KDE Plasma 5.26.1 running X11 or Wayland fails to start, after logging in from SDDM: * The cursor works, but no panel shows up, the desktop starts to freeze, i.e. turns gray after a while * Pressing CTRL+ALT+DEL opens the power-management overlay, where logging out works * Shutting down the system does not work after having logged in once, but takes infinitely long and requires a forced shut down Going back to kernel 6.0.2 fixes the issue. An interesting part of the journalctl is likely the following: ``` 09:56:43 kernel: BUG: kernel NULL pointer dereference, address: 00000000000001c8 09:56:43 kernel: #PF: supervisor write access in kernel mode 09:56:43 kernel: #PF: error_code(0x0002) - not-present page 09:56:43 kernel: PGD 0 P4D 0 09:56:43 kernel: Oops: 0002 [#1] PREEMPT SMP NOPTI 09:56:43 kernel: CPU: 16 PID: 1419 Comm: rasdaemon Tainted: G O 6.0.3-1-default #1 openSUSE Tumbleweed 50a6ebc5cb1873d6b9c639843cdd1ed0089a1281 09:56:43 kernel: Hardware name: System manufacturer System Product Name/ROG STRIX X570-E GAMING, BIOS 4204 02/24/2022 09:56:43 kernel: RIP: 0010:ring_buffer_wake_waiters+0x1c/0xa0 09:56:43 kernel: Code: 48 39 d0 73 ed 0f 0b eb e9 0f 1f 44 00 00 55 48 89 fd 53 48 63 de 83 fb ff 74 36 48 8b 47 40 48 8b 1c d8 48 81 c3 78 01 00 00 <48> 83 43 50 01 31 c9 31 d2 48 8d 7b 20 be 03 00 00 00 e8 cd af f3 09:56:43 kernel: RSP: 0018:ffffaa7a815a7e20 EFLAGS: 00010206 09:56:43 kernel: RAX: ffff908c434db500 RBX: 0000000000000178 RCX: 0000000000000010 09:56:43 kernel: RDX: ffff908c78ed8000 RSI: 0000000000000018 RDI: ffff908c434da900 09:56:43 kernel: RBP: ffff908c434da900 R08: ffff908c50b82e00 R09: ffff908c8206b200 09:56:43 kernel: R10: 0000000000000000 R11: 0000000000000001 R12: ffff908c8206b200 09:56:43 kernel: R13: ffff908c4387ef20 R14: ffff908c90fddbc0 R15: 0000000000000000 09:56:43 kernel: FS: 00007fd7463a6340(0000) GS:ffff90934ee00000(0000) knlGS:0000000000000000 09:56:43 kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 09:56:43 kernel: CR2: 00000000000001c8 CR3: 0000000105574000 CR4: 0000000000750ee0 09:56:43 kernel: PKRU: 55555554 09:56:43 kernel: Call Trace: 09:56:43 kernel: <TASK> 09:56:43 kernel: tracing_buffers_release+0x49/0x90 09:56:43 kernel: __fput+0x91/0x250 09:56:43 kernel: task_work_run+0x5c/0x90 09:56:43 kernel: exit_to_user_mode_prepare+0x1cb/0x1f0 09:56:43 kernel: syscall_exit_to_user_mode+0x17/0x40 09:56:43 kernel: do_syscall_64+0x67/0x80 09:56:43 kernel: ?
