Some recent update around February or March if I recall caused this issue to arise on my Lenovo X201. The iwn WiFi had been working reliably for maybe a year before that. It occurs on both 11.3-RELEASE and 12.1-RELEASE. I swapped in a disk from another machine to test 11.3. The iwn WiFi works fine for a while after a cold or warm boot, then suddenly goes dark after anywhere from a few minutes to maybe half an hour and logs the following: May 24 11:57:39 mako kernel: iwn0: iwn_read_firmware: ucode rev=0x09dd0401 May 24 12:45:07 mako kernel: iwn0: iwn_read_firmware: ucode rev=0x09dd0401 May 24 12:50:34 mako kernel: iwn0: device timeout May 24 12:50:34 mako kernel: iwn0: iwn_read_firmware: ucode rev=0x09dd0401 May 24 12:50:34 mako kernel: iwn0: iwn_hw_init: could not power ON adapter, error 60 May 24 12:50:34 mako kernel: iwn0: iwn_init_locked: could not initialize hardware, error 60 I confirmed that it's a FreeBSD regression and not a hardware failure by installing Debian on this machine. Debian has its own set of issues, but the Intel WiFi works reliably.

can you help figure out which release or head snapshot it last /did/ work in? That'd help narrow things down. Thanks!
Did a little more investigation and it appears the problem arose with the release of 12.1. I did a fresh 12.1 install with no base updates and it does exhibit the problem. I don't have written records, but I think I had run both 11.2 and 12.0 on this machine without any WiFi issues.
(In reply to Jason W. Bacon from comment #2) That points at r346037, which is a rather large commit unfortunately. iwm has gotten a number of updates since 12.1, so it would also be worth testing a recent stable/12 kernel.

Didn't see the last response until now. I'll try 12.2-RC for starters.
Still happening on 12.2-RC2. The frequency of the issue has gone down since it first appeared. It was generally happening within minutes when it first appeared, but much less frequently since the latest 12.1-RELEASE updates. Today it ran all day with 12.2-RC1 before going down this evening.
I'm running 12.2-RC3 now and haven't seen the issue in weeks. I'll consider it resolved and reopen if it reappears.
