Is fw signed? Do I need to sign it with my MOK? Use the upstream repo to get the files. The files aren't signed. https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/ The `dmesg` command will tell you which firmware files it's trying to load. Then DL that(/those) file(s) from the repo and put them in /lib/firmware/ Then on next boot the kernel will find them. > -rw-r--r-- 1 root root 1369976 2024-04-03 21:24 > iwlwifi-QuZ-a0-hr-b0-73.ucode -rw-r--r-- 1 root root 1371668 2024-04-03 > 21:24 iwlwifi-QuZ-a0-hr-b0-74.ucode -rw-r--r-- 1 root root 1404184 > 2024-04-03 21:24 iwlwifi-QuZ-a0-hr-b0-77.ucode > > (2) About kernel experiments, unfortunately it is a production server with > samba-ad and ad replication.

That isn't available on Stable, but grabbing ``firmware-iwlwifi`` from Testing should be safe. Not sure if that version is new enough though. https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/ is the upstream repo and you could 'grab' the firmware files which `dmesg` reports it can't find. > -- System Information: > Debian Release: 12.5 > APT prefers stable-security > APT policy: (500, 'stable-security'), (500, 'stable') > Architecture: amd64 (x86_64) > > Versions of packages linux-image-6.1.0-18-amd64 is related to: > ii firmware-amd-graphics 20230210-5 > pn firmware-atheros > pn firmware-bnx2 > pn firmware-bnx2x > pn firmware-brcm80211 > pn firmware-cavium > ii firmware-intel-sound 20230210-5 > pn firmware-intelwimax > pn firmware-ipw2x00 > pn firmware-ivtv > ii firmware-iwlwifi 20230210-5 My guess is that those 'backported' patches expect newer firmware then that. signature.asc Description: This is a digitally signed message part.

Package: src:linux Version: 6.1.76-1 Severity: important Tags: upstream Dear Maintainer, *** Reporter, please consider answering these questions, where appropriate *** The driver fills the eventlog with millions !!! of messages, see below. It otherwise works. The problem can be reproduced on different NUC systems. These are used as small servers, run a network bridge and hostapd. There is no evidence that the problem depends on hostapd. When the connection is idle the rate of reported errors goes down to a few 10 per second. A larger stream of data (2GByte or so) produces seveeral hundered tousand messages. * What led up to the situation? iwlwifi is loaded with parameters as described in the debian wiki for AX201 / Intel Nuc hardware: options iwlwifi 11n_disable=8 options iwlmvm power_scheme=1 without power_scheme it frequently drops connections, with power_scheme=1 it is stable. The effect of 11n_disable is unknown. * What exactly did you do (or not do) that was effective (or ineffective)? Needed to increase network message_cost to reduce logging: echo 128 > /proc/sys/net/core/message_cost * What was the outcome of this action? * What outcome did you expect instead? A driver that simply works. *** End of the template - remove these template lines *** -- Package-specific info: ** Version: Linux version 6.1.0-18-amd64 (debian-ker...@lists.debian.org) (gcc-12 (Debian 12.2.0-14) 12.2.0, GNU ld (GNU Binutils for Debian) 2.40) #1 SMP PREEMPT_DYNAMIC Debian 6.1.76-1 (2024-02-01) ** Command line: root=LABEL=alpha1_vol0 rootflags=subvol=/Volumes/Root-bookworm ro resume=alpha1_swap centauriswitch=static:apoint net.ifnames=0 mitigations=off security= quiet splash loglevel=3 ** Not tainted ** Kernel log: [30911.569896] BTRFS info (device sda4): disk space caching is enabled [30974.905443] net_ratelimit: 67420 callbacks suppressed [30974.905457] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [30974.905728] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [30974.906036] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [30974.906356] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [30974.906681] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [30974.907014] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [30974.907319] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [30974.907576] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [30974.908421] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [30974.908744] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31102.906916] net_ratelimit: 216171 callbacks suppressed [31102.906930] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31102.911063] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31102.911481] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31102.911817] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31102.912118] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31102.912434] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31102.912758] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31102.913054] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31102.913376] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31102.913728] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31230.911440] net_ratelimit: 221524 callbacks suppressed [31230.911453] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31230.911815] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31230.912192] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31230.912511] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31230.912895] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31230.913217] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31230.913562] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31230.913912] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31230.914255] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31230.915740] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31358.912228] net_ratelimit: 213726 callbacks suppressed [31358.912240] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31358.912554] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31358.912873] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31358.914335] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31358.914433] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31358.914948] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31358.915097] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31358.915459] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31358.915749] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31358.916034] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31486.915992] net_ratelimit: 205539 callbacks suppressed [31486.916005] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31486.923781] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31486.924153] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31486.924548] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31486.924860] iwlwifi :00:14.3: Unhandled alg: 0x33f0707 [31486.925252] iwlwifi :00:14.3: Unhandled alg: 0x33f0707
