boot dmesg

I have an Intel 9560 on my ThinkPad X1 Carbon Gen7 and in dmesg the init fails here:

iwm0: <Intel(R) Dual Band Wireless AC 9560> mem 0xea238000-0xea23bfff at device 20.3 on pci0
iwm0: fw chunk addr 0x404000 len 712 failed to load
iwm0: iwm_pcie_load_section: Could not load the [0] uCode section
iwm0: iwm_start_fw: failed 60
iwm0: Failed to start INIT ucode: 60

I see that some work was done in FreeBSD for the 9560 since 12.1-RELEASE, and I appreciate the efforts! I just want it to be known that while the device is actually detected this time, the firmware fails to load, so that possibly this problem can be rectified in time for the full release. I have attached a full dmesg here:

Thanks!

None of your dmesg parts seems to be from a boot verbose.

Can you please share the output of
   pciconf -lBbcevV iwm0

I guess a verbose dmesg would be more helpful, so I've attached it here. Here's the `pciconf -lBbcevV iwm0` output:

Update:
I booted 12.2-BETA2 today, and I noticed something VERY interesting with the wifi problem. It seems the firmware ucode load only fails if you reboot from Linux straight to FreeBSD. If I fully shut down the laptop and then boot the 12.2-BETA2 installer image, iwm0 starts up with no issues and I can even connect to wifi networks. So it seems there's only some kind of bug after a reboot from linux to freebsd now, it may be worth looking into.

Once you've power cycled and got it working in FreeBSD, does it still work after a quick reboot?

Yes, I forgot to mention but once I got wifi working on FreeBSD and I rebooted back to FreeBSD, everything worked just fine once again.

I've installed 12.2-BETA2 on another USB and I've noticed that while connected to wifi my speeds are barely 2 Mbit/s download and 0.21 Mbit/s upload using https://github.com/sivel/speedtest-cli, but the same tool reports 88.24 Mbit/s and 55.14 Mbit/s on the same machine running void linux, so it isn't just my internet speed. I hope I'm not coming off as complaining too much, I'd just like to help polish this stuff out through testing. I imagine certain logs/files may be helpful, but I just don't know what those would be.

iwm(4) currently only does abg and no 11n or 11ac.  We hope to rectify this with the iwlwifi port over which will also support the newer hardware from Intel before the end of the year.

I'd prefer not to conflate two issues in the bug report, so let's keep this one focused on the startup issues (for whoever is going to look into that).
