This normally means that the driver that handles the keyboard hardware can't properly handle power management events(sleep/wakeup).

Possible solutions and workarounds:

* Contact the system manufacturer for support(if they do)
* Find the problematic driver that handles the keyboard and disable its power management functionality entirely(sacrificing power for functionality) using custom udev rules.

We need to determine the cause of the problem in order to deal with it properly, which isn't a trivial task to tell you it's possible or not directly.

Which means it's possibly a regression occured in the new kernel/driver, you may use bisect technique to pinpoint the exact kernel version/revision that introduces that regression in order for the kernel maintainers to fix the bug, though this is also not a trivial task for regular users and require you to learn how to build a kernel from source and testing it.

As an alternative workaround, you can also try manually installing the known good old kernel, which may or may not remedy your problem.

You can find the older kernel packages by going to the packages.ubuntu.com site and filter the 22.04 distro version and packages whose name started with the linux- prefix.

That is also a probable workaround, though note that the 22.04 version has a support period of 5 years which will end in 2027. Refer the ubuntu releases wiki page for the exact date you must migrate to newer distri releases.

If you in a rather little chance happen to be in Taiwan at 6/1 we have a Ubuntu Release Party held at the MozTW Space which you can brought your system to have it checked by our community members.
