[PSA] LM19C kernel update to 4.15.0.177.166 borked my keyboard

Post by Reorx »

I am running LM 19.0 Cin on several laptops... I recently updated the kernel on 2 of them to the most current available kernel - 4.15.0.177.166. On both laptops this upgrade resulted in my keyboard becoming non-functional at boot up so I was unable to login to a session. The mouse was working normally so I shut down the machine and rebooted it... this time selecting the previous kernel and everything worked correctly. I then deleted the 177.166 kernel and rebooted. Everything is now back to "normal".

I am not looking for a solution, I am just publishing this "glitch" for others who may run into it and come here looking for more info...

Safe travels,

Hello, Reorx.

I am running Linux Mint 19.3 Cinnamon or xfce with kernel 4.15.0-177#186 on 3 different machines:
+ a Packard Bell laptop - keyboard is the built-in keyboard
+ an Acer Aspire notebook - keyboard is the built-in keyboard
+ a Medion desktop machine - external keyboard
None of the 3 keyboards exhibits any problems at startup time or later on, since the kernel was updated to K4.15.0-177#186.

Also, your report is the first report, where kernel 4.15.0-177#186 is suspected to cause a keyboard to malfunction, which I come about. Seems to suggest this problem cannot be a common problem affecting a larger number of machines and keyboards.

Therefore it must be assumed that the problem, which you experiences, is related to the specific keyboard, which you use.
Therefore it would be helpful if you shared your Linux Mint System Information with us. (How to can be found > here <)
Therefore it would be helpful if you told us more about the precise keyboard type and how it is connected to your machine.

Regards,
Karl

Karl;

Thanx for the reply... I have since googled the the kernel and there are several hits describing various problems... one was that the kernel was having a hard time "finding" a wifi card and was 'searching" for about 90 seconds before continuing. I didn't wait very long to see if my cursor showed up...

In terms of connection, it is a standard laptop with a standard laptop keyboard type of connection...

As I said, I'm not looking for a solution, this is just a PSA to point out a known problem... there is another thread or 2 here (I found on google after I posted this thread) discussing some other problems associated with this kernel version as well...

Hello, Reorx.

So your keyboard, which does not work when booting kernel 4.15.0-177 is the built-in Dell notebook keyboard, not a second external keyboard, attached through USB. Correct?

Regards,
Karl

Hello, Reorx.

Found the following bug reports about kernel 4.15.0-177 on Ubuntu Launchpad: All bug reporters seem to agree that reverting to kernel 4.15.0-176 resolved the problems, introduced by kernel 4.15.0-177.

Yes, that is correct! :mrgreen:

Yep, that was my experience as well. :mrgreen:

No mistake. Look at your update history for a kernel update. See also examples >>>

Hi,

the Ubuntu kernel version strings can be confusing. Admitted.
The kernel software package linux-image-4.15.0-177-generic has got the full version string 4.15.0-177.186.
The corresponding kernel meta package linux-generic, however, has got the full version string 4.15.0.177.166.
The command uname -a displays the kernel version as 4.15.0-177-generic #186-Ubuntu.

So we are all talking about the same kernel version, only picking the rightmost 3 digits from different kernel packages.

Cheers,
Karl

Follow up:

A kernel upgrade was offered today in Mint Update so I tried it - I upgraded (on one of the two machines in question) the kernel to 4.15.0.180.189. After a quick reboot, everything seems to be working as usual. I'll report back after I do the second of the 2...

6/8/2022 update: After a few days of use it became apparent the the .180 kernel also had problems as did the next kernel in the 4.15 series (.184). After rolling back my kernel and deleting the problematic ones, I have black listed kernel updates for the series. As a practical matter, LM19 is approaching EOL and all my LM19 machines will be upgraded to LM21 in a few months.

Cheers! :mrgreen:

Same here, sound and wifi stopped working after upgrading to kernel 4.15.0-180 (where previously 4.15.0-177 also failed)

Multiple people with problems with this kernel have found switching to the latest 5.4 kernel resolves the issue.

The 5.4 kernel is available in Update Manager. View>Linux Kernels and click Continue.
