Re: [REGRESSION] bluetooth: mt7921: Crash on Resume From Suspend And Hibernate

Sergio,

My apologies, I neglected to mention that my setup is PCI, and not USB.

It's an AMD Ryzen 5 7600 CPU on a PRO B650M-A Wifi motherboard. For completeness OS is Fedora 40
with any kernel starting with 6.11.x.

    $ lspci | grep MEDIATEK
    0c:00.0 Network controller: MEDIATEK Corp. MT7922 802.11ax PCI Express Wireless Network Adapter

    $lshw -C Network

What I am struggling to understand is given how easy this issue is to reproduce -  an AMD CPU, Mediatek MT7922 wifi/bluetooth chip,
and a 6.11 kernel, you suspend, and then wake up, kernel panics -  I would have thought that the interested parties would
make this a priority.

I think that a logical first step would be for SW owners to confirm (or deny) the anomalous behavior.

Thanks,

John
