** Description changed:
- I have a brand new LeNovo legion Y540 and the ideapad_laptop module
- results in a rfkill.
+ === SRU Justification ===
+ [Impact]
+ WiFi on Ideapads are rfkill HW blocked by default.
+
+ [Fix]
+ Remove no_hw_rfkill_list as most Ideapads don't have hardware rfkill
+ button.
+
+ [Test]
+ User reported the fix works.
+
+ [Regression Potential]
+ Low. If there's any actual device that has HW rfkill button, we can
+ simply add it to whitelist.
+
+ === Original Bug Report ===
+ 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
+ sudo rfkill
ID TYPE DEVICE SOFT HARD
