[Issue]: Hang on linux-6.6.5.arch1-1

mozlima commented 9 months ago

Hi, on the latest Arch kernel linux 6.6.5.arch1-1, the adapter is experiencing freezing and only reverting to linux-6.6.4.arch1-1 and linux-headers-6.6.4.arch1-1 fix the problem

I did test:

usb_modeswitch: freeze
iw dev: freeze
sudo dmesg: freeze
iwd: freeze
network manager+iwd: freeze
network manager+wpa_supplicant: freeze

The computer only shuts down by pulling the power cable, since usb_modeswitch fail to shutdown.

Hi @mozlima

the adapter is experiencing freezing and only reverting to linux-6.6.4.arch1-1 and linux-headers-6.6.4.arch1-1 fix the problem

Over the last few days, I have noticed an abnormal number of bug reports from arch users and all seem to be related to kernel 6.6.5. It is not yet clear to me what may be the problem but this very well could be an arch issue as I am not seeing this on the distros I currently have up for testing here. You might want to post on an arch forum to see if you can find additional info. If you get more info, please let me know.

I'm experiencing the same issue. Not sure if it is the exact same problem but this thread seems to suggest that it is an Arch kernel issue that affects more than this driver.

The fix on #25 of that thread works for me.
