Linux kernel regression on net/mac80211/cfg.c

[stream009 <stream009@xxxxxxxxx>]

Hi, I'd like to report a regression on the linux kernel.
This is the first time I report bug on the linux kernel, and I am not familiar
with how to do it properly, so I am sorry if I send this to a wrong person.

The regression seems to be a year old, but still exists in the latest kernel.

- Symptom
    The Kernel halts after resuming from sleep mode.

- Condition
    There has been no problem in kernel version 6.8.9 which I keep using almost
    a year for a reason. Then when I upgrade system and kernel become version
    6.13.8, the problem started to occur.

- Diagnosis
    - "Oops" message on kernel log.
    - "Oops" almost always happen around hostapd.
    - I am using USB Wifi adaptor to make my PC Wifi access point. I have been
      having a problem that my Wifi AP stop working after the resume, so I set
      up systemd so that it restarts hostapd automatically after the system
      resume from the sleep. This workaround has been working for a long time
      until now. It seems this restart of hostapd after the resume triggers
      the "Oops" and subsequent halting of the kernel. I confirm this hypothesis
      by stopping hostapd before the sleep and see there is no problem
restarting
      it after the resume.
    - By conducting kernel bisections on the source from linux-stable
repository,
      I pinpoint the commit 1c0d21c4b33a41be9090e73f8225813d72ac88d9 to be the
      first commit that produce the problem.

The Wifi adaptor I am using is WLI-UC-G300HP, which is driven by the
driver rt2800usb.

I attach files that seems relevant:
    - A kernel log that contains "Oops".
    - A git bisection log.
    - A kernel .config file.

Please tell me if I am missing something to help you solving the issue.
