ideapad_laptop disables WiFi/BT radios on Lenovo Y530
Status in linux package in Ubuntu:
Confirmed
Bug description:
I've been working with a user that has a Lenovo Legion Y530-15ICH
where booting Ubuntu 18.10 (kernel 4.18.0-8) results in the radios
being disabled by the platform driver "ideapad-laptop".
Unloading or blacklisting the module solves the issue but disables
other platform ACPI interfaces:
$ sudo tee /etc/modprobe.d/ideapad.conf <<< "blacklist ideapad_laptop"
The system has the most recent firmware:
[0.00] DMI: LENOVO 81FV/LNVNB161216, BIOS 8JCN44WW 08/13/2018
The wifi device is:

[Jefferson Peak] [8086:a370] (rev 10)
Subsystem: Intel Corporation Wireless-AC 9560 [Jefferson Peak] [8086:0034]
Kernel driver in use: iwlwifi
We investigated the issue extensively and built the module with
additional logic without solving the issue. It is well-known that some
Lenovo models do not have a separate hardware radio kill switch (this
model uses hot-keys Fn + F7 for 'Airplane mode') and need to use a DMI
match to disable the rfkill logic.

[Kernel-packages] [Bug 1797772] Re: ideapad_laptop disables WiFi/BT radios on Lenovo Y530
By the way. I went to linux kernel 5.2.1 ideapad_laptop.c and now
there's no no_hw_rfkill_list. It's the opposite, now it has to be
specified if there is a hw-rfkill. So that new laptops don't get this
problem.
One option is to install a ppa with a recent kernel.
>From the file:
* Some ideapads have a hardware rfkill switch, but most do not have one.
* Reading VPCCMD_R_RF always results in 0 on models without a hardware rfkill,
* switch causing ideapad_laptop to wrongly report all radios as hw-blocked.
* There used to be a long list of DMI ids for models without a hw rfkill
* switch here, but that resulted in playing whack a mole.
* More importantly wrongly reporting the wifi radio as hw-blocked, results in
* non working wifi. Whereas not reporting it hw-blocked, when it actually is
* hw-blocked results in an empty SSID list, which is a much more benign
* failure mode.
* So the default now is the much safer option of assuming there is no
* hardware rfkill switch. This default also actually matches most hardware,
* since having a hw rfkill switch is quite rare on modern hardware, so this
* also leads to a much shorter list.

[Kernel-packages] [Bug 1797772] Re: ideapad_laptop disables WiFi/BT radios on Lenovo Y530
I solved it in my Y540 by compiling a new ideapad_laptop with dkms
adding "legion Y54015IRH" to the no_hw_rfkill_list.
This post and bug 1811815 helped me quite a bit, so, thank you.

[Kernel-packages] [Bug 1797772] Re: ideapad_laptop disables WiFi/BT radios on Lenovo Y530
Hi TJ, do you still have the machine? Can it be fixed with the similar
approach as you did in bug 1811815?

ideapad_laptop disables WiFi/BT radios on Lenovo Y530
Status in linux package in Ubuntu:
Confirmed
Bug description:
I've been working with a user that has a Lenovo Legion Y530-15ICH
where booting Ubuntu 18.10 (kernel 4.18.0-8) results in the radios
being disabled by the platform driver "ideapad-laptop".
Unloading or blacklisting the module solves the issue but disables
other platform ACPI interfaces:
$ sudo tee /etc/modprobe.d/ideapad.conf <<< "blacklist ideapad_laptop"
The system has the most recent firmware:
[0.00] DMI: LENOVO 81FV/LNVNB161216, BIOS 8JCN44WW 08/13/2018
The wifi device is:

Kernel driver in use: iwlwifi
We investigated the issue extensively and built the module with
additional logic without solving the issue. It is well-known that some
Lenovo models do not have a separate hardware radio kill switch (this
model uses hot-keys Fn + F7 for 'Airplane mode') and need to use a DMI
match to disable the rfkill logic.

[Kernel-packages] [Bug 1797772] Re: ideapad_laptop disables WiFi/BT radios on Lenovo Y530
It was a clean install of 18.10. The mainline module doesn't have
support for this device as yet. Since the blacklist the user has gone
quite so additional testing is not possible

[Kernel-packages] [Bug 1797772] Re: ideapad_laptop disables WiFi/BT radios on Lenovo Y530
Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.19 kernel[0].
If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.
If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".
Thanks in advance.

Title:
ideapad_laptop disables WiFi/BT radios on Lenovo Y530
Status in linux package in Ubuntu:
Incomplete
Bug description:
I've been working with a user that has a Lenovo Legion Y530-15ICH
where booting Ubuntu 18.10 (kernel 4.18.0-8) results in the radios
being disabled by the platform driver "ideapad-laptop".
Unloading or blacklisting the module solves the issue but disables
other platform ACPI interfaces:
$ sudo tee /etc/modprobe.d/ideapad.conf <<< "blacklist ideapad_laptop"
The system has the most recent firmware:
[0.00] DMI: LENOVO 81FV/LNVNB161216, BIOS 8JCN44WW 08/13/2018
The wifi device is:
00:14.3 Network controller [0280]: Intel Corporation Wireless-AC 9560
[Jefferson Peak] [8086:a370] (rev 10)
Subsystem: Intel Corporation Wireless-AC 9560 [Jefferson Peak] [8086:0034]
Kernel driver in use: iwlwifi
We investigated the issue extensively and built the module with
additional logic without solving the issue. It is well-known that some
Lenovo models do not have a separate hardware radio kill switch (this
model uses hot-keys Fn + F7 for 'Airplane mode') and need to use a DMI
match to disable the rfkill logic.
We used dmidecode to get the correct Version string:

[Kernel-packages] [Bug 1797772] Re: ideapad_laptop disables WiFi/BT radios on Lenovo Y530
** Description changed:
I've been working with a user that has a Lenovo Legion Y530-15ICH where
booting Ubuntu 18.10 (kernel 4.18.0-8) results in the radios being
disabled by the platform driver "ideapad-laptop". Unloading or
blacklisting the module solves the issue but disables other platform
ACPI interfaces.
The system has the most recent firmware:
[0.00] DMI: LENOVO 81FV/LNVNB161216, BIOS 8JCN44WW 08/13/2018
The wifi device is:
00:14.3 Network controller [0280]: Intel Corporation Wireless-AC 9560
[Jefferson Peak] [8086:a370] (rev 10)
- Subsystem: Intel Corporation Wireless-AC 9560 [Jefferson Peak]
[8086:0034]
- Kernel driver in use: iwlwifi
+ Subsystem: Intel Corporation Wireless-AC 9560 [Jefferson Peak] [8086:0034]
+ Kernel driver in use: iwlwifi
We investigated the issue extensively and built the module with
additional logic without solving the issue. It is well-known that some
Lenovo models do not have a separate hardware radio kill switch (this
model uses hot-keys Fn + F7) and need to use a DMI match to disable the
rfkill logic.
We used dmidecode to get the correct Version string:
Handle 0x0001, DMI type 1, 27 bytes

and added it to no_hw_rfkill_list[]:

However, rfkill was still listing the platform devices "ideapad_wlan"

We then added printk(KERN_NOTICE ... in the module's
platform_driver.probe function ideapad_acpi_add() both at entry and
later to report the DMI and status of the hardware switch control flag:
