Thanks. Could you please try the attached patch?
Your patch doesn't help, same errors. Thank you. I'm not able to reproduce this on a laptop with a 8265 chip. You might try seeing if reverting r361662 fixes the problem. And of course, make sure that the rfkill switch is not actually engaged. :) I installed FreeBSD into this laptop (Lenovo Thinkpad E540) in February 2020 and wireless never works after suspend-resume. So my problem is not related to r361662. Pressing wireless switch on keyboard (Fn+F8) doesn't make any difference. Only reboot needed. hi! Just try disabling the rfkill path totally: edit if_iwm_pcie_trans.c, go to the function named iwm_check_rfkill() and change "return rv" to "return 0". I dont' know if the hardware is active or not at this point, but at least we'll know it's not because it's getting a spurious rfkill interrupt or something. hi!

Disabling rfkill doesn't change anything. May be it's related to some ACPI issue? (In reply to Alexandr Krivulya from comment #9) Could you try to debug it further? E.g., you can add printf-s to see why the code decides that "radio is disabled by hardware switch" and so on. Nobody else can reproduce this problem, so unless you debug your issue, there's a little chance that it would be fixed. It is not reproducible any more, so may be closed. Thank you. |
