I can't find a way how to reproduce this issue. I've reproduced this issue in versions 6.6 6.7 and 6.8 May be new systemd version cause this issue... kernel: BUG: unable to handle page fault for address: 0000000000004bfa kernel: #PF: supervisor read access in kernel mode kernel: #PF: error_code(0x0000) - not-present page kernel: PGD 0 P4D 0 kernel: Oops: 0000 [#1] PREEMPT SMP PTI kernel: CPU: 0 PID: 604 Comm: systemd Tainted: P U O 6.6.21-gentoo #1 kernel: Hardware name: LENOVO 20H9CTO1WW/20H9CTO1WW, BIOS N1VET64W (1.54 ) 07/14/2023 kernel: RIP: 0010:rb_first+0xb/0x30 kernel: Code: 66 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 40 00 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 48 8b 07 48 85 c0 74 18 48 89 c2 <48> 8b 40 10 48 85 c0 75 f4 48 89 d0 31 d2 31 ff c3 cc cc cc cc 31 kernel: RSP: 0018:ffffc90001df7ca8 EFLAGS: 00010202 kernel: RAX: 0000000000004bea RBX: ffff88815b645480 RCX: 0000000000000000 kernel: RDX: 0000000000004bea RSI: 0000000000000000 RDI: ffff88815b6656c8 kernel: RBP: ffff88815b74b800 R08: 0000000000000000 R09: 0000000000000000 kernel: R10: 0000000000000000 R11: 0000000000000000 R12: 0000000000000000 kernel: R13: ffff88815b6656c8 R14: 0000000000000000 R15: ffffffffa332e9f8 kernel: FS: 00007f1650c34900(0000) GS:ffff888490600000(0000) knlGS:0000000000000000 kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 kernel: CR2: 0000000000004bfa CR3: 000000011537c001 CR4: 00000000003706f0 kernel: Call Trace: kernel: <TASK> kernel: ? __die+0x1f/0x70 kernel: ? page_fault_oops+0x15d/0x460 kernel: ? __kmem_cache_alloc_node+0x2aa/0x430 kernel: ? cgroup_file_open+0x4b/0x130 kernel: ? exc_page_fault+0x387/0x5f0 kernel: ? asm_exc_page_fault+0x22/0x30 kernel: ? rb_first+0xb/0x30 kernel: simple_xattrs_free+0x25/0xa0 kernel: kernfs_put.part.0+0x60/0x150 kernel: kernfs_remove_by_name_ns+0x7d/0xd0 kernel: cgroup_addrm_files+0x28e/0x320 kernel: ? step_into+0x10/0x750 kernel: ? __pfx_percpu_ref_switch_to_atomic_rcu+0x10/0x10 kernel: ? rcu_is_watching+0xd/0x40 kernel: css_clear_dir+0x4b/0xd0 kernel: cgroup_destroy_locked+0xb1/0x1c0 kernel: cgroup_rmdir+0x27/0xe0 kernel: kernfs_iop_rmdir+0x4c/0x80 kernel: vfs_rmdir+0x76/0x1f0 kernel: do_rmdir+0x13c/0x180 kernel: __x64_sys_rmdir+0x3e/0x80 kernel: do_syscall_64+0x59/0x90 kernel: ? do_syscall_64+0x68/0x90 kernel: entry_SYSCALL_64_after_hwframe+0x6e/0xd8 kernel: RIP: 0033:0x7f165172c507 kernel: Code: f0 ff ff 73 01 c3 48 8b 0d 1e 99 0c 00 f7 d8 64 89 01 48 83 c8 ff c3 66 2e 0f 1f 84 00 00 00 00 00 66 90 b8 54 00 00 00 0f 05 <48> 3d 00 f0 ff ff 77 01 c3 48 8b 15 f1 98 0c 00 f7 d8 64 89 02 b8 kernel: RSP: 002b:00007ffcf6c399d8 EFLAGS: 00000246 ORIG_RAX: 0000000000000054 kernel: RAX: ffffffffffffffda RBX: 0000000000000000 RCX: 00007f165172c507 kernel: RDX: 0000000000000000 RSI: 0000000000000001 RDI: 000055f4cef1eb10 kernel: RBP: 000055f4ceecd840 R08: 00000000ffffffff R09: 0000000000000000 kernel: R10: 0000000000000000 R11: 0000000000000246 R12: 00007f1651adcc41 kernel: R13: 0000000000000001 R14: 0000000000000000 R15: 000055f4cee6e080 kernel: </TASK> kernel: Modules linked in: udp_diag tls tcp_diag inet_diag usbhid wireguard curve25519_x86_64 libchacha20poly1305 chacha_x86_64 poly1305_x86_64 libcurve25519_generic libchacha tun snd_seq_dummy snd_hrtimer snd_s> kernel: intel_pch_thermal roles ledtrig_audio platform_profile usb_common snd tpm_tis soundcore i2c_hid_acpi tpm_tis_core i2c_hid tpm intel_wmi_thunderbolt wmi_bmof think_lmi firmware_attributes_class i915 cec > kernel: CR2: 0000000000004bfa kernel: ---[ end trace 0000000000000000 ]--- kernel: RIP: 0010:rb_first+0xb/0x30 kernel: Code: 66 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 40 00 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 48 8b 07 48 85 c0 74 18 48 89 c2 <48> 8b 40 10 48 85 c0 75 f4 48 89 d0 31 d2 31 ff c3 cc cc cc cc 31 kernel: RSP: 0018:ffffc90001df7ca8 EFLAGS: 00010202 kernel: RAX: 0000000000004bea RBX: ffff88815b645480 RCX: 0000000000000000 kernel: RDX: 0000000000004bea RSI: 0000000000000000 RDI: ffff88815b6656c8 kernel: RBP: ffff88815b74b800 R08: 0000000000000000 R09: 0000000000000000 kernel: R10: 0000000000000000 R11: 0000000000000000 R12: 0000000000000000 kernel: R13: ffff88815b6656c8 R14: 0000000000000000 R15: ffffffffa332e9f8 kernel: FS: 00007f1650c34900(0000) GS:ffff888490600000(0000) knlGS:0000000000000000 kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 kernel: CR2: 0000000000004bfa CR3: 000000011537c001 CR4: 00000000003706f0 kernel: note: systemd[604] exited with irqs disabled

(In reply to Mike Pagano from comment #4) > Anything to report here ? This issue reproducing with nvidia-drivers-550 Works stable ithout nvidida-drivers or with nvidia-drivers-535 version.
Known issue with nvidia drivers
>kernel: Hardware name: LENOVO 20H9CTO1WW/20H9CTO1WW, Nothing I can do about this, but pretty sure it's the same as $URL so you can track progress there. Lenovo laptop users should stick to 535 meanwhile (even after 550 is stabilized, which will happen given it's a production branch, becoming overdue, and this does not affect most hardware). Note 535 will be around for a long time as it's still supported by nvidia and getting bugfix/security updates and we're not removing it until that stops.
