And how about CPU frequencies? power usage when normal was around 3W and during the pause the graph drops = to about 1/2 of normal.

Sorry - was running kernel 6.17 which does not have messages.=20=20 I re-tested with kernel 6.19 When sitting in a virtual terminal that is running "dmesg -w" I see previous messages, but when I sit there for 10 minutes there were no additional messages. Conclusion: when sitting in virtual terminal there are no pauses and no messages. > GPU throttling may also lead to the same effects, which we can't rule out > yet. You can monitor GPU statistics with amdgpu_top's GUI, which provides > graphs so that you can check them after a pause. Don't have time right now to figure out the proper way to install amdgpu_to= p, if it is needed I will have to come back to that. Let me know if this beco= mes important to your investigation. > Yes, triggering magic sysrq to see stacktraces in dmesg during the pause > event is very helpful and reveals what's going on. On my laptop Fn-S is sysrequest so I am using keyboard commands for trigger= ing - much easier than trying to setup SSH - thanks for suggesting this option! in normal UI I do the following: open terminal and run "sudo sysctl kernel.sysrq=3D1" to enable the magic ke= yboard stuff and then "dmesg -w" so I can see kernel messages and copy them Use alt-(Fn-S)-l to trigger dump when pause happens - see following dump wi= th the error message immediately following.
