Good time of day!
Sorry for bothering you, I found a strange bug in "intel_vbtn" kernel
module which makes the keyboard non-responding.
Reproducible 100% starting from kernel 5.4.0-45 and till 5.8.0-20.
Everything works fine on 5.4.0-42 or on Windows 10
As a workaround I blacklisted the intel_vbtn module and everything works
fine. Seems like it somehow relative to tablet mode detection patch.
I did research and found out that this bug is affecting Acer Aspire E5-511G
laptops and some HP model(s).
Here it is: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1894017
Looking forward to hearing something from you.
Thanks for your attention!
Thank you for your bug report.
This should be fixed by this upstream commit, which landed in Linus' tree a couple of hours ago:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/platform/x86?id=8169bd3e6e193497cab781acddcff8fde5d0c416
Igor, if you do:
cat /sys/class/dmi/id/chassis_type
On your laptop, and the output is NOT "31" or "32" then this
fix should work for you.
If the output actually is "31" or "32 (which I do not expect),
then please let me know, because then we need a different fix.
I've also added this comment to the launchpad bug.
Regards,
Hans
