Restarting 0x2000000. iwlwifi 0000:06:00.0: Microcode SW error detected. Restarting 0x82000000. This is a major issue since driver crashes repeatedly. Only today I had 370 (!) crashes and since Oct 25 there was 1400 crashes. I am attaching the most recent series of crash.

Created attachment 307834 [details] latest firmware Hi Maxim, Can you please try the firmware attached? Just copy it to /lib/firmware. Your problem seems to be a firmware problem, and there were a few changes that are not included in your version. I can't tell that your issues will be fixed, but since you reproduce easily, it's worth trying. Thanks!

Can't say yet that it fixes the issue but it now fails at the start, which wasn't the case for older firmware. See an attachment. Wifi still works after the fail but I don't think it's the intended behaviour. It is different failure though. Firmware does change: [ 20.033550] iwlwifi 0000:06:00.0: loaded firmware version 36.f82a4177.0 8265-36.ucode op_mode iwlmvm Old one: [ 42.279192] iwlwifi 0000:06:00.0: loaded firmware version 36.ca7b901d.0 8265-36.ucode op_mode iwlmvm
Very strange... Can you tell what happened on October 25th? Firmware update? Kernel update? New router?

New error log from dmesg in attachment. > Can you tell what happened on October 25th? Not sure if it has any meaning. Could be just journald not having logs any earlier. But at 24th there was a kernel upgrade: linux (6.11.4.arch2-1 -> 6.11.5.arch1-1) linux-lts (6.6.57-1 -> 6.6.58-1) And firmware upgrade on 18th: linux-firmware (20240909.552ed9b8-1 -> 20241017.22a6c7dc-1) Router is the same, but there was a relatively big fw upgrade month before: https://mikrotik.com/download/changelogs#c-stable-v7_16 Can't say for sure if I updated the same day or a month before so it could be the reason too.
I talked to the firmware team and they think this problem is caused by a frame that we started to receive. This device is fairly old but I can try to see if we can get some attention from them. We'd need a firmware dump: https://wireless.docs.kernel.org/en/latest/en/users/drivers/iwlwifi/debugging.html#firmware-debugging Note the privacy implications. You can encrypt the data if you want.
I've installed debug firmware (36.9f0a2d68.0) from this page. When there's enough info I will report. Also FYI intel cards, even newer ax200/ax201 do seem to be flacky with routeros: https://forum.mikrotik.com/viewtopic.php?p=1129079 https://forum.mikrotik.com/viewtopic.php?p=1117936 I am not implying that my issue is the same though. But thought it is worth to note.
