            Bug ID: 260014
           Summary: rtwn0: timeout waiting for firmware readiness
           Product: Base System
           Version: 13.0-STABLE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: wireless
          Assignee: wireless@FreeBSD.org
          Reporter: marko.cupac@mimar.rs

Hi,

I'm getting the following error in dmesg on my laptop running 13.0-STABLE #0
n248076-3a15ccadf87:

rtwn0: timeout waiting for firmware readiness

Wifi performance is almost unusable.

I found this error described in rtwn(4) manpage:

     rtwn%d: timeout waiting for firmware readiness  Firmware upload failed;
     the file might be corrupted.  The driver will disable firmware-dependent
     features.  This should not happen.

I'm fairly convinced this is not about corrupted file, as I just built world
and kernel yesterday (GENERIC), mostly no problems with other stuff. I am
running stable because I need drm-devel-kmod in oder to have working
modesetting driver on this laptop (ThinkPad T14 AMD 1st gen).

Any help highly appreciated.
