@toekneefan I know the workforce is always limited and I don't want to

Now that the new SOF firmware is included in the linux-firmware package
(see bug #1900809) the audio stack has been much more stable for me.
Unfortunately there has been still one audio stack crash after the
firmware upgrade, but it probably was another issue, since the dmesg
didn't contain
This update would also fix at least bug #1881505.
Basically, my audio on Lenovo T14 was working very unreliably and jammed
with a DSP panic quite often with the 1.4.2 version, but seems to work
just fine with 1.6.
It would be great to get this update included soon, since it's very
inconvenient
It seems that the 1.6 version of the SOF firmware fixes the issue for
me. Haven't got any of those DSP panic messages anymore after the update
and before the update they occurred almost every day.
Is there anything I can do to help in making this fix to be included to
linux-firmware package?
If this is indeed the same issue as in
https://github.com/thesofproject/sof/issues/2828, then the problem
should be fixed by upgrading the SOF firmware to 1.6 version.
I'll give it a try by installing directly from
https://github.com/thesofproject/sof-bin/tree/stable-v1.6
I will let you know if
I have the same problem with Lenovo T14 (Gen 1), which seems to have a

On Ubuntu 20.04 stable,
the Clipit interface does not work on Xorg either. The hotekeys do not work,
the preferences do not open and the program does not shut down properly.

that the cause of the problem described here was actually not due to

Hi!
Would it be possible to apply these patches for the trusty kernel so
that the next LTS would fully work on the new Haswell based Chromebooks
(Acer C720, HP Chromebook 14) out of the box? Currently and without
these patches e.g. touchpad doesn't work.
No need to gather logs, it's just a request for new hardware enablement
in the kernel. These patches have been submitted to upstream for merge,
but haven't been merged yet to submaintainer tree and Linus tree.
