iwlwifi kernel panics, Wireless 7260, main-n275833-136c5e17b61a (2025-03-07)

<https://cgit.freebsd.org/src/log/?qt=range&q=136c5e17b61a> 136c5e17b61a from pkgbase base_latest. First panic today, Saturday 2025-03-08 02:18, in response to service netif restart wlan1 at home with ssid 'piano5'. Photographed five minutes after the command (whilst the computer was visibly frozen, non-responsive, before the automated restart of the OS): <https://imgur.com/gb4WQJ7>. For the first of the panics: I can not offer a backtrace, sorry. IIRC the second panic occurred after the savecore for the first; during automated generation of the crash summary. It seems that the third panic occurred during the next start of the OS, probably after the savecore and successful crash summary for the second panic. core.txt.14 (02:42, for a panic at 02:28) might contain enough for me to match it to something in Bugzilla. (Off-topic from freebsd-wireless: crashinfo(8) can not produce a useful core.txt.13 file.) For a few hours before the panics, on Friday, I had limited success with iwlwifi(4) with eduroam. Then at home, some panic-free experiments with a different ssid (piano). After the series of panics (with piano5), I reverted to iwm(4). root@mowa219-gjp4-zbook-freebsd:/var/crash # less core.txt.13 root@mowa219-gjp4-zbook-freebsd:/var/crash # crashinfo vmcore.13 Writing crash summary to ./core.txt.13. root@mowa219-gjp4-zbook-freebsd:/var/crash # less core.txt.13 root@mowa219-gjp4-zbook-freebsd:/var/crash # cat info.13 Dump header from device: /dev/ada1p2 Architecture: amd64 Architecture Version: 2 Dump Length: 2706395136 Blocksize: 512 Compression: none Dumptime: 2025-03-08 02:18:33 +0000 Hostname: mowa219-gjp4-zbook-freebsd Magic: FreeBSD Kernel Dump Version String: FreeBSD 15.0-CURRENT main-n275833-136c5e17b61a GENERIC-NODEBUG Panic String: page fault Dump Parity: 3349005578 Bounds: 13 Dump Status: good root@mowa219-gjp4-zbook-freebsd:/var/crash # ls -hlnrt | grep 8\ 08 -rw------- 1 0 0 2.8G Mar 8 08:12 kgdb151.core -rw-r--r-- 1 0 0 8.6K Mar 8 08:12 core.txt.13 root@mowa219-gjp4-zbook-freebsd:/var/crash # exit logout grahamperrin:~ % pciconf -lv | grep -A 3 iwm iwm0@pci0:61:0:0: class=0x028000 rev=0x6b hdr=0x00 vendor=0x8086 device=0x08b1 subvendor=0x8086 subdevice=0xc060 vendor = 'Intel Corporation' device = 'Wireless 7260' class = network grahamperrin:~ % bectl list -c creation | tail -n 6 1500034-002-ports - - 54.8M 2025-03-04 13:48 1500034-003-base-ports - - 1.30G 2025-03-05 01:18 1500034-004-ports - - 59.9M 2025-03-05 11:48 1500034-005-base - - 925M 2025-03-06 07:00 1500034-006-base - - 1006M 2025-03-07 09:40 1500034-007-base NR / 233G 2025-03-07 12:56 grahamperrin:~ % tail -n 6 /home/grahamperrin/Documents/boot\ environments.txt 1500034-002-ports 2025-03-04 13:48 main-n275770-6ba1c5abb957 GENERIC-NODEBUG 397957f38f35159b9774623b9522d57eddf5e648 1500034-003-base-ports 2025-03-05 01:18 main-n275791-ca48e43ba9ee GENERIC-NODEBUG c0ddb80a45d83268d27896df705cf1e009bd3f43 1500034-004-ports 2025-03-05 11:48 main-n275791-ca48e43ba9ee GENERIC-NODEBUG c0ddb80a45d83268d27896df705cf1e009bd3f43 1500034-005-base 2025-03-06 07:00 main-n275806-27bf5c405bf2 GENERIC-NODEBUG a9da0bcfd2f01fbdc86d37ce697b94a6cb6cbd16 1500034-006-base 2025-03-07 09:40 main-n275820-b8dfc3ecf703 GENERIC-NODEBUG 1a660da9f33417bb50c01a5b7f663a4992aedbd2 1500034-007-base 2025-03-07 12:56 main-n275833-136c5e17b61a GENERIC-NODEBUG e385de4e8451d91b453fc751b9d238625d961c25 grahamperrin:~ % root@mowa219-gjp4-zbook-freebsd:/var/crash # ls -hlnrt | tail -n 11 -rw-r--r-- 1 0 0 11K Dec 31 04:24 core.txt.12 -rw------- 1 0 0 421B Mar 8 02:27 info.13 -rw------- 1 0 0 82M Mar 8 02:27 vmcore.13 -rw-r--r-- 1 0 0 3B Mar 8 02:41 bounds -rw------- 1 0 0 421B Mar 8 02:41 info.14 -rw------- 1 0 0 1.4G Mar 8 02:42 vmcore.14 lrwxr-xr-x 1 0 0 7B Mar 8 02:42 info.last -> info.14 lrwxr-xr-x 1 0 0 9B Mar 8 02:42 vmcore.last -> vmcore.14 -rw-r--r-- 1 0 0 230K Mar 8 02:42 core.txt.14 -rw------- 1 0 0 2.8G Mar 8 08:12 kgdb151.core -rw-r--r-- 1 0 0 8.6K Mar 8 08:12 core.txt.13 root@mowa219-gjp4-zbook-freebsd:/var/crash # grep BOOT /var/log/messages Mar 8 02:27:43 mowa219-gjp4-zbook-freebsd kernel: ---<<BOOT>>--- Mar 8 02:34:24 mowa219-gjp4-zbook-freebsd kernel: ---<<BOOT>>--- Mar 8 02:41:45 mowa219-gjp4-zbook-freebsd kernel: ---<<BOOT>>--- Mar 8 03:48:23 mowa219-gjp4-zbook-freebsd kernel: ---<<BOOT>>--- Mar 8 06:27:05 mowa219-gjp4-zbook-freebsd kernel: ---<<BOOT>>--- root@mowa219-gjp4-zbook-freebsd:/var/crash #
