Hi scholbert,

Yes I'm seeing 100% CPU on jitterentropy with 5.11 as well. Not good! Also seeing 100% on another core with systemd-devd, so that's two cores fully consumed. Yuck.

I'm not using sleep (I'm actually running with phosh disabled for a specific project) so I don't know if the modem is getting lost.

Now I have to choose between fast charging via convergence dock (5.11) or having > 50% CPU cores available (5.10). Sigh.

Regards,
GregH

Guys, please contribute your experiences with the power issues on 5.10 in order to try to get it fixed: https://gitlab.com/mobian1/issues/-/issues/176

Yup - jitterentropy running 100% as soon as I boot.

What is really weird is this happened on a new Mobian I just cooked using the Debos recipes.

My previous Mobian was also cooked via Debos but possibly in January sometime, and update && upgrade since then. As well as all kinds of other experimenting. When I added 5.11 on that I did not have the jitterentropy problem, nor did I have any problem with the modem waking from sleep. (Didn't run the new brew long enough to see if I had any modem waking problems.)

Thanks for the heads up. I noticed the phone hadn't gone into suspend after receiving a call and the battery had drained a lot.
Also have the 100% jitterentropy. I hadn't noticed the modem loss on suspend though I had that issue with Manjaro Plasma Mobile after doing updates so no doubt that explains it as well!

I edited /boot/extlinux/extlinux.conf to boot on 5.10 instead of 5.11 for now.

Just ran an update/upgrade and found that jitterentropy has been updated (to 1.2.1-2) - and the CPU usage is no longer being thrashed on 5.11 Big Grin

i have been seeing 5.11 for while during my updates but it wasn't until today that i am officially Linux mobian 5.11-sunxi64 #1 SMP PREEMPT Thu Mar 11 15:34:35 UTC 2021 aarch64 GNU/Linux when i rebooted after upgrade and issued uname -a. Right away though i am having trouble getting my mini laptop on line via usb tethering Sad .
This is one thing i rely on with Pine phone. Do i need to go back to 5.10? Thank you!

(04-13-2021, 10:19 AM)I had to reinstall  the 20210210 version to get back to the easy and unsecured ways  of doing things. I\m  now back to 5.10 #2.   The USB tethering worked again. Also annoying thing in 5.11 is how  the Bluetooth turns on randomly, which is not right.   HLing Wrote: i have been seeing 5.11 for while during my updates but it wasn't until today that i am officially  Linux mobian 5.11-sunxi64 #1 SMP PREEMPT Thu Mar 11 15:34:35 UTC 2021 aarch64 GNU/Linux when i rebooted after upgrade and issued uname -a.  Right away though i am having trouble  getting my mini laptop on line via usb tethering Sad .
