Crash with iwlwifi Error
-
I installed an Intel AX210-based card into my box running 23.01-RELEASE but have been seeing this in my logfile and then losing functionality of the interface:
Mar 22 kernel iwlwifi0: Scan failed! ret -5
Mar 22 kernel iwlwifi0: ERROR: lkpi_ic_scan_start: hw_scan returned -5I typically can get the card working by removing the interface assignment, removing the wireless interface, and then reinstalling. However, I cannot rename the interface or I loose functionality and I cannot restart the router or I loose functionality. Additionally, whatever is causing this error sometimes crashes the router. I have posted the dumpfile here: https://pastebin.com/fiwiXSPh.
Can anybody comment on what might be causing this and how to fix it?

S stephenw10 moved this topic from General pfSense Questions on

That's a driver fault, so something upstream.
Seems related to this:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=262150
Or this:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=261075But both those are marked fixed and should be in 23.01. iwlwifi is pretty new though there could well be further issues.

Actually it looks exactly like this: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=266570
But also see: https://bugs.freebsd.org/bugzilla/buglist.cgi?quicksearch=iwlwifi

@stephenw10 Aside from waiting for FreeBSD updates, is there anything I can do to work toward a solution for this (e.g., upgrade firmware, etc.)?
-
No, I don't expect anything to really help there until there is an update from upstream. Unless maybe there is some workaround found. But that would also be from upstream FreeBSD users since there may be no-on else but you using it in pfSense.
To move forward I would try to test the hardware in FreeBSD 14 directly and then report any issues upstream.

@stephenw10 Appreciate the guidance!
