Title:
System hangs after attaching Mediatek mt76x2u based USB Wifi network
adapter
Status in linux package in Ubuntu:
Incomplete
Bug description:
After attaching a Mediatek mt76x2u based USB Wifi network adapter the
system (Ubuntu 20.04.1 LTS linux version 5.4.0-58-generic) hangs
My findings after some testing:
- A freshly installed Ubuntu 20.04 (for testing purposes) with an outdated
kernel 5.4.0-26 is not affected as the USB Wifi network adapter works without
any problems.
- After updating this system to kernel version 5.4.0-58 the problem can be
reproduced.
- After upgrading to Ubuntu 20.10 with kernel version 5.8.0-33 the USB Wifi
network adapter works without any problems.
So I guess it could be a software problem (maybe linux-image oder
linux-modules?).
