Kernel 5.15

[Zebulon Walton]

I just noticed that with the Mobian updates installed tonight it looks like kernel 5.15 was installed. Previously the phone was running on 5.13 which I had installed manually.

I was alerted to the kernel upgrade by a popup message after installing updates saying that the /boot partition was full. Checking it I saw the 5.10, 5.13, and 5.15 kernels were there. (I removed the old 5.10 kernel to free up space. Space on /boot is quite limited and old, unused kernels are not purged automatically.)

Running "cat /proc/version" after rebooting confirms that the phone is now running on the 5.15 kernel. Does the new kernel bring any noticeable improvements?

Huh, cat /proc/version shows 5.10 on mine. Wonder if it's worth changing to 5.15, and how I get it to do that. I started with Bullseye, and upgraded to Bookworm, and have been upgrading every week or so, with a dist-upgrade or two along the way.

What's it take to get it to upgrade the kernel?

It fixes the video output bug. So if you couldn't get video on a monitor before it should now work.

Just regular

Code:

sudo apt update && sudo apt upgrade

Should I also delete the 5.13 kernel to free up more space on /boot? On a regular desktop system if something happens to the newest kernel I can select an older one to boot up on (if present) via the grub menu. I'm not sure if it's possible to do that on the Pinephone.

I don't know, but you can check how much space you have left on your partitions with:

Code:

df -h

I noticed that after this update my phone has trouble going to sleep, which decreases battery life. Dmesg:

I'd delete 5.13 once you're happy 5.15 works adequately. I think you'd need to use the serial cable to pick an alternate kernel in u-boot as AFAIK it doesn't know about the screen or buttons. p-boot can present a full boot menu, but I don't think any of the distros are using it other than Megous' multiboot image, so you would need to update the boot menu manually on kernel updates.

I can not confirm the sleep issues on my phone.

Sorry guys, this is so funny. So distro packagers just push new kernel versions and don't care how much space is left on your phones ?
This is so simple to find out in the script.

This is a perfect example why this device will never get "popular". It's already going down. I'm not going to say a word about how "open" it is. Just think about this modem having proprietary software.

hehhe

All phone modems have proprietary software. What makes this phone different is that the operating system is free.

No suspend problems on FDE-Mobian...

And thanks @beta_user for anti-trolling.
