That looks to be the problem here. Can you test on FreeBSD 11.2, please? And if you haven't, compiling the driver with IWM_DEBUG enabled and the if-test later on in that file commented out so all prints are enabled might give some more insights.

I'll ask the FreeBSD folks if they know anything about this, though.

comment:3 by korli, 15 months ago

I tested with the FreeBSD 11.2 memstick, the driver doesn't show up. I've verified the stick with the laptop with the Atheros wlan device, it works there. I've checked in /var/log/messages, no iwm related messages there. Any idea to get more logs in FreeBSD?

comment:4 by waddlesplash, 15 months ago

I know there are some sysctls to enable more logging, but these only work after boot has completed, and so probably are not useful. You might need to manually enable a firmware if they haven't enabled it by default; but I've never had to do that so I'm not sure. (Maybe find me on IRC?)

comment:5 by waddlesplash, 15 months ago

There are some commits in OpenBSD and DragonFlyBSD that might fix this. One of the FreeBSD developers said that he plans to cross-merge those within the next few weeks; so waiting for that might make sense.

comment:6 by korli, 15 months ago

I tried 12.0-CURRENT, same behavior. Then I tried "kldload if_iwm", the driver is loaded, the correct firmware module appears loaded when listing with kldstat. I could then create the wlan interface, but wpa_supplicant returns an error about interfacing the driver.

Maybe it would be better to remove the PCI id involved in a release.

comment:8 by waddlesplash, 14 months ago

Well, if it doesn't KDL, what's the harm?

comment:9 by waddlesplash, 10 months ago

So, I have actually seen this occur on my hardware now; it seems intermittent. On some reboots it happens 100% of the time, on others it never happens and I have WiFi. Talking to the FreeBSD guys, it seems the iwm driver is just very flaky in general...

Please retest after hrev52722.

comment:11 by waddlesplash, 9 months ago

If you haven't yet, please retest after hrev52792.

Resolution: fixed
Status: newclosed

At least I haven't seen those controller panics anymore after that commit, so, closing as fixed.
