Hi!
My system was running fine, no errors in the logs, and then it started
to happen, an infinite flow of oops in the kernel logs.
The bug seems to happen in "__ieee80211_scan_completed" and it seems to
involve the firmware: "Microcode SW error detected. Restarting",
"ieee80211 phy0: Hardware restart was requested" and "iwlwifi
0000:02:00.0: FW error in SYNC CMD SCAN_REQ_UMAC".
Since then, the iwlwifi module oops all the time, even after unloading
and reloading it.
My system:
NixOS 23.11
Linux 6.6.3
Intel(R) Wi-Fi 6 AX210 160MHz, REV=0x420
firmware version: 83.e8f84e98.0 ty-a0-gf-a0-83.ucode
Here's the logs attached and more info about my system.
I tried very hard to get decode_stacktrace.sh to works with module
symbols but the NixOS file hierarchy makes things quite difficult.
I can try again if needed.
Sincerly,
Paul Grandperrin

Hi Paul,
Can you please open a bug in Bugzilla, so we can handle it there?
Please attach there a sniffer capture and a trace-cmd log.
This is how to: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/debugging
Thanks,
Miri
Sorry, last time I openned a bug there, there was no answers, only the
mailing list was monitored.
I opened https://bugzilla.kernel.org/show_bug.cgi?id=218239
