Looking at bug 218305, I haven't noticed if the issue is triggered by suspend/resume or restart cycles. I'm on a laptop that regularly goes throu= gh several days of use before being rebooted, so it's possible. I'll keep an e= ye out to see if that's related. From what I experienced, the issue would occur while using the machine for a few hours, and the issue would "fix" itself u= pon a suspend/resume or restart. As far as similarities to bug 218305, I'm also running a Ryzen APU (on Zen 3 and not 4) on an HP Dev One, which I believe is a modified Elitebook 845 G8= or G9. However, I've been told by HP support and the System76 team they outsou= rced the project to that the firmware on the Dev One was custom written for the project and unrelated to the standard Elitebook line's firmware. I also use `ryzenadj` to set STAPM, PPT FAST and SLOW limits. Like in bug 218305, I also leave my laptop plugged in the majority of the time. When I experience the issue again, I'll look at more diagnostics to see if = it's like bug 218305.=20 > What is your CPU scaling governor when it happened?=20 I use the amd-pstate-epp driver in active mode, and alternate between the powersave and performance governors depending on whether I'm on battery pow= er or not, and delegate that switch to power-profiles-daemon versus using sysf= s. It's happened while on AC power, so it is likely I was using the performance governor when I experienced the issue. --=20 You may reply to this email to add a comment.
