Bug Description

The iwlwifi driver is logging microcode crashes on a daily basis. The chip is Intel 9462 (AX201). Ubuntu release 22.04 LTS, faithfully kept up to date.

Crash log is different from what I've found by googling, and for similar errors the firmware version is much more recent. Here's the log output from crash (leaving some extra lines there as well to show the chip and firmware version):

I'm not sure what happened but I did the following:
- Disabled Bluetooth
- Switched to another access point
- Used the PC for some time
- Noticed I wasn't getting these errors any more, and decided I want to reproduce the issue
- Re-enabled Bluetooth
- Switched back to original access point
-> Still not observing a microcode crash with the same signature. I do get microcode crashes but those are a different story.

Firmware is still the same version and access point is still using the same firmware version as well. Another nearby access point has been updated to a new firmware version but that shouldn't matter here as when the failures occurred the computer wasn't connected to that AP.

Until I figure out how to reproduce the same failure it's probably impossible to find and fix this.
