does anyone knows what's the root cause of this issue/bug ? I've had the exact same problems and I suspect it's because of my wi-fi card drivers / 6.4 kernels and onwards

basically: frequent wifi disconnects, complete unrecoverable system crashes during high network activity, and no sysrq responses afterwards. logs say nothing

Wifi stops working followed by whole system freeze

This seems similar to a situation I encountered that I had attributed to a failing wifi adapter and solved by replacing the adapter. About the time kernel 6.4 was released I began getting periodic and intermittent freezes followed by a crash and reboot. I discovered that I was having a cpu going into deadlock that was the symptom of the freeze and crash. Eventually over some time I traced it down to the wifi repeatedly disconnecting and reconnecting but it became apparent that those repeated ...

@kouett I had once problems with a usb to ethernet dongle. This was something with drivers, because after sitting for a long time in a drawer, the device became usable.

What I've concluded from the issues I had, is once something inside kernel network stack locks up, the whole system fails, because a lot of internal communication goes over unix domain sockets. There's no way around it.

You may try to find some clues in dmesg. You can search http://bugzilla.kernel.org/ and make a report if there's none.
