Kernel 4.15.0-151 causes major problems

[grayro]

Hi, I am running Linux Mint Mate 19.1 on a Lenovo T480 laptop. Within the past two days (I believe after a kernel update) my laptop has started acting strangely. Often it fails to boot. When it does boot the mouse is frozen, or I am unable to change the volume, Firefox crashes, etc. The current kernel is 4.15.0-151. When I instead boot with kernel 4.15.0-147, all of those problems go away. My laptop is dual boot and I am not experiencing any problems with Windows either. So, I can carry on, but it is clear that the 151 kernel has some major problems. I may try an upgrade to 19.3 if necessary, but I have no other current reason to upgrade. I cannot find any other place to report this kernel bug.

Without some technical information, we can’t help you. Please post an inxi -Fxxxzr report. This will give us a concise overview of your hardware and how Mint sees it.

Here is how to generate the report and post it:
Open a terminal window (Ctrl-Alt-t). Make it fullscreen to avoid unneeded linebreaks or chopped lines. Execute the command

Code: Select all

 inxi -Fxxxzr 

exactly as it has been typed here.

Mark the complete text output which the command will display with your mouse.
Press the keyboard shortcut <Shift><Ctrl>C to copy the marked text into the clipboard.
Enclose the results between the code markers by selecting </> from the mini toolbar above the textbox where you type your reply then paste <Ctrl>V them in your reply between the code markers [code]Results [/code].

The results will help us to help you.

Welcome to the forum, Richard.

This forum is where users help other users. Kernel bugs go on launchpad.

One way to report bugs is to open Update Manager, select View > Linux Kernels and then click continue. Then select 4.15 in the left pane and click on a kernel in the right pane. When you do that, the first link which appears is bug reports. That link takes you to the list of bugs already reported on that specific kernel. You can add a new bug (if yours is not listed) by clicking the "Report a Bug" link in the upper right.

Since you may have removed the -151 kernel already, here is a post with two bugs reported on 4.15.0-151. I do not have the 4.15 kernel, so I can not provide the direct link to the bugs for 4.15.0-151.

Thank you for your reply. Here is the information for my system. Of course, this was done while booted into the 147 Kernel.

Thank you. I found a number of bug reports related to Kernel 151 via the Update Manager. I see that there is already a beta kernel -- 153 -- which seems to be working for some people. So, I will continue to use 147 until 153 is available.

Thank you for your patience and kind help.

I may try an upgrade to 19.3 if necessary, but I have no other current reason to upgrade.

Richard Gray

Hi Richard, I'm running 19.3 and getting the same problems so don't think an upgrade would make any difference for you.
Getting the occasional app freeze, but lock up on boot more often. Typically happening on the login screen and the only way out is a hard power off, which I don't like doing.

I'm going to revert back to an earlier kernel, but thought I'd let you know that 19.3 also affected.

Thanks for the information!
