Kernel:HEAD 6.9rc breaks iwlwifi on Thinkpad T480
Last modified: 2024-04-20 16:15:33 UTC
I'm running current Tumbleweed on my "new" Thinkpad T480 using iwlwifi. I have both KOTD kernel-default-6.9-rc and Tumbleweed's kernel-vanilla-6.8.x installed, the latter as a way to recover if KOTD breaks :-) Since the first 6.9-rc releases, my WIFI does not work. mixi:~ # uname -a Linux mixi 6.9.0-rc4-2.g4804f5c-default #1 SMP PREEMPT_DYNAMIC Mon Apr 15 08:48:25 UTC 2024 (4804f5c) x86_64 x86_64 x86_64 GNU/Linux mixi:~ # ip link set up dev wlp3s0 RTNETLINK answers: Invalid argument mixi:~ # rfkill ID TYPE DEVICE SOFT HARD 0 bluetooth tpacpi_bluetooth_sw blocked unblocked 1 wlan phy0 unblocked unblocked mixi:~ # ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host noprefixroute valid_lft forever preferred_lft forever 2: wlp3s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noqueue state DOWN group default qlen 1000 link/ether 92:df:96:3e:36:0b brd ff:ff:ff:ff:ff:ff permaddr 38:ba:f8:f4:ed:63 3: enp0s31f6: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000 link/ether 8c:16:45:fc:09:b0 brd ff:ff:ff:ff:ff:ff seife@mixi:~> dmesg|grep iwl [ 9.948811] iwlwifi 0000:03:00.0: Detected crf-id 0xbadcafe, cnv-id 0x10 wfpm id 0x80000000 [ 9.948978] iwlwifi 0000:03:00.0: PCI dev 24fd/0010, rev=0x230, rfid=0xd55555d5 [ 10.187732] iwlwifi 0000:03:00.0: loaded firmware version 36.ca7b901d.0 8265-36.ucode op_mode iwlmvm [ 10.637788] iwlwifi 0000:03:00.0: Detected Intel(R) Dual Band Wireless AC 8265, REV=0x230 [ 10.701153] iwlwifi 0000:03:00.0: base HW address: 38:ba:f8:f4:ed:63, OTP minor version: 0x4 [ 10.779246] ieee80211 phy0: Selected rate control algorithm 'iwl-mvm-rs' [ 10.784000] iwlwifi 0000:03:00.0 wlp3s0: renamed from wlan0 [ 17.419360] iwlwifi 0000:03:00.0: Registered PHC clock: iwlwifi-PTP, with index: 1 The dmesg regarding anything wifi (not only iwlwifi) does not differ from the working 6.8.x kernels, no additional error or missing line or anything. I have no idea how to debug this any further, I would not even know what to report upstream ;-) The Thinkpad T480 should still be in use in high numbers, so I wonder how I can be the only one seeing this issue? hwinfo for the card: 41: None 00.0: 10701 Ethernet [Created at net.126] Unique ID: Mqes.ndpeucax6V1 Parent ID: hAO_.xdVuDfcpKg9 SysFS ID: /class/net/wlp3s0 SysFS Device Link: /devices/pci0000:00/0000:00:1c.6/0000:03:00.0 Hardware Class: network interface Model: "Ethernet network interface" Driver: "iwlwifi" Driver Modules: "iwlwifi" Device File: wlp3s0 HW Address: 92:df:96:3e:36:0b Permanent HW Address: 38:ba:f8:f4:ed:63 Link detected: no Config Status: cfg=new, avail=yes, need=no, active=unknown Attached to: #1 (Ethernet controller)
As it's a 6.9-rc regression, the best would be to contact with the upstream devs. Care to post to linux-wireless ML? You can get the regression tracking involved, too (for catching more attention).
Yes, I can do that. I was just a bit hesitant as I have basically no information at all and thus was hoping you would already have heard something about that problem ;-) I'll come back here after talking to the wireless ML

Thanks for the info!
