Description Jason W. Bacon freebsd_committer 2020-06-03 19:46:29 UTC
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.

Specs:

Jun  3 14:25:38 manatee kernel: iwn0: <Intel Centrino Advanced-N 6200> mem 0xf2400000-0xf2401fff irq 16 at device 0.0 on pci3

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.
