Public bug reported:
I have a brand new LeNovo legion Y540 and the ideapad_laptop module
results in a rfkill.
If the module is removed/blacklisted, then wifi works, but some ACPI
functionality is lost (the fans don't spin correctly and the laptop
doesn't cool properly).
I will try to compile ideapad_laptop adding the laptop info to
no_hw_rfkill_list[].
I only tried in ubuntu 19.10 (although this is a kernel issue)
rfkill output:
sudo rfkill
ID TYPE DEVICE SOFT HARD
2 bluetooth hci0 blocked unblocked
3 wlan phy0 unblocked unblocked
4 wlan ideapad_wlan unblocked blocked
5 bluetooth ideapad_bluetooth blocked blocked
1) Ubuntu 5.0.0-20.21-generic 5.0.8
(rest of info in attachment)
