Anyone having issues with the 6.14.0-28 kernel

Support and Help
1

Hi, is anyone seeing issues with the 6.14.0-28 kernel? I’m running Ubuntu 25.04, and this kernel was a recent update. I’m seeing these odd issues with the cp command after running sudo aptitude safe-upgrade -y.

If I try to boot into the new kernel, my laptop gets a PSOD (purple screen of death).

Are you using the rust coreutils (uutils)? If so, does updating that help?

Please also show us the output of these commands:

which cp
cp --version

Thanks for the suggestions.

$ which cp
/usr/bin/cp

$ cp --version
cp 0.0.30

I had previously enabled the rust based tools with oxidizer. Ironically, I’ve had not noticed an issue until now. All the tools I regularly use with coreutils seem to work outside of this cp -Z.

Are you able to upgrade to version 0.1.0?

Version 0.1.0 of which package? I regularly do a sudo apt update && sudo aptitude safe-upgrade -y. I did not notice any available updates.

I did try a sudo oxidizr disable, but I still couldn’t get update-initramfs to complete successfully.

Since this was a test box, I reloaded Ubuntu 25.04. It’s running the 6.14.0-28-generic kernel without an issue now with the tradition GNU coreutils back in place.
