[Bug 1217495] New: WiFi fails to re-connect on return from suspend, occasionally.
https://bugzilla.suse.com/show_bug.cgi?id=1217495 Bug ID: 1217495 Summary: WiFi fails to re-connect on return from suspend, occasionally. Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.5 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Network Assignee: screening-team-bugs@suse.de Reporter: carlos.e.r@opensuse.org QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- Created attachment 870981 --> https://bugzilla.suse.com/attachment.cgi?id=870981&action=edit journal showing the event Some times, when thawing my laptop, it fails to connect to the WiFi. Looking at the log, this might look a router issue, but the thing is, it has happened to me on two routers, one in Ottawa, another in Madrid. And hibernating the machine makes the WiFi connect again (power cycles the chipset). Thus I believe the problem is in the laptop/linux side, not the router. Laptop is less that a year old, a Lenovo L14 Gen3 AMD. I will attach journal showing one such incident. Some lines removed for privacy.

I finally got around to try, but what I did was install Leap 15.6 alpha in the test partition of the laptop (openSUSE-Leap-15.6-DVD-x86_64-Build623.2-Media.iso). Unfortunately, the kernel oopses when I try to connect via WiFi (NM hangs, and the command "ip addr" hangs subsequently, and can not be killed; Machine has to be rebooted, it is not stable. When told to poweroff, machine hangs at BIOS logo and I have to powercycle). Do you want that as a separate bug, or shall I put the log here? I'm just pasting the first oops: localhost systemd[1]: Starting Hostname Service... localhost dbus-daemon[2350]: [system] Successfully activated service 'org.freedesktop.hostname1' localhost systemd[1]: Started Hostname Service. localhost dbus-daemon[3578]: [session uid=1000 pid=3578] Activating via systemd: service name='ca.desrt.dconf' unit='dconf.service' requested by ':1.25' (uid=1000 pid=3759 comm="nm-applet --indicator ") localhost systemd[3555]: Starting User preferences database... localhost dbus-daemon[3578]: [session uid=1000 pid=3578] Successfully activated service 'ca.desrt.dconf' localhost systemd[3555]: Started User preferences database. kernel: [ 6330.120788][ T2612] wlan0: authenticate with 70:8b:cd:59:88:3c kernel: [ 6330.140578][ T2612] BUG: kernel NULL pointer dereference, address: 0000000000000000 kernel: [ 6330.140590][ T2612] #PF: supervisor read access in kernel mode kernel: [ 6330.140598][ T2612] #PF: error_code(0x0000) - not-present page kernel: [ 6330.140606][ T2612] PGD 0 P4D 0 kernel: [ 6330.140614][ T2612] Oops: 0000 [#1] PREEMPT SMP NOPTI kernel: [ 6330.140625][ T2612] CPU: 4 PID: 2612 Comm: wpa_supplicant Tainted: G n 6.4.0-150600.8-default #1 SLE15-SP6 6283f681587a79afbd508a1baf0e7b98911578d4 kernel: [ 6330.140640][ T2612] Hardware name: LENOVO 21C5CTO1WW/21C5CTO1WW, BIOS R1YET40W (1.17 ) 01/10/2023 kernel: [ 6330.140648][ T2612] RIP: 0010:mt7921_mgd_prepare_tx+0x6f/0xa0 [mt7921_common] kernel: [ 6330.140671][ T2612] Code: ff e8 65 91 82 cd 4c 89 f6 48 89 ef e8 8a ab f4 ff 49 8b 84 24 38 04 00 00 49 8b bc 24 78 07 00 00 0f b7 cb 4c 89 ee 45 31 c0 <48> 8b 10 e8 19 fe ff ff 48 89 ef 4c 89 f6 e8 8e ac f4 ff 4c 89 ff kernel: [ 6330.140690][ T2612] RSP: 0018:ffffa5b0c1677758 EFLAGS: 00010246 kernel: [ 6330.140698][ T2612] RAX: 0000000000000000 RBX: 00000000000003e8 RCX: 00000000000003e8 kernel: [ 6330.140707][ T2612] RDX: 0000000000000000 RSI: ffff95affcf820d0 RDI: ffff95b0124c7400 kernel: [ 6330.140715][ T2612] RBP: ffff95b0124c2060 R08: 0000000000000000 R09: ffffa5b0c1677608 kernel: [ 6330.140723][ T2612] R10: 0000000000e92004 R11: ffffffffc199da80 R12: ffff95affcf81ca0 kernel: [ 6330.140732][ T2612] R13: ffff95affcf820d0 R14: ffff95b0124c9cf8 R15: ffff95b0124c2610 kernel: [ 6330.140739][ T2612] FS: 00007f1429626800(0000) GS:ffff95b68ec00000(0000) knlGS:0000000000000000 kernel: [ 6330.140749][ T2612] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 kernel: [ 6330.140757][ T2612] CR2: 0000000000000000 CR3: 000000013b882000 CR4: 0000000000f50ee0 kernel: [ 6330.140765][ T2612] PKRU: 55555554 kernel: [ 6330.140771][ T2612] Call Trace: kernel: [ 6330.140778][ T2612] <TASK> kernel: [ 6330.140787][ T2612] ?
