Modules crashes on loading #156

Open onprem opened 4 years ago

onprem commented 4 years ago

When I boot the laptop, sometimes the module crashes during the initial load, and sometimes it gets loaded successfully but then after some time it crashes. I was able to capture the stacktrace. Let me know if you need something else.

Happens in my system too. In my case, it crashes on unload, and then crashes on load again.

The driver crashes at 10:57:50, after running rmmod, then crashes again at 10:57:59. First crash shows "hal/rtl8821c/rtl8821c_halinit.c:122 rtl8821c_power_off+0x62/0x8d [rtl8821ce]" as the last call. Second crash shows "hal/rtl8821c/rtl8821c_halinit.c:93 rtl8821c_power_on+0x4c/0x8f [rtl8821ce]".

BTW @prmsrswt: we have the same hardware. Maybe this is something specific to these ASUS laptops?
