I am too, but this one is too visible to make generic. > I guess very few Linux users will object if it doesn't blow up everything > else. Well it's a pretty big behavior change. I found that when it is in place if I close my lid and then open it immediately I can't wake up immediately because that 2.5s hasn't passed yet to even start the suspend. Or if I close my lid before putting a laptop in the bag I would expect all the fans stop before I put it in the bag. Well now you close your lid and the fans are still running? That makes you think there is a problem, so you open it back up to check. If we're going to keep "some" variation of it around for everyone I would rather it be on an interruptible timer, which means maybe putting it somewhere earlier in the sequence that interrupts are still enabled. I don't really know what could be different with what Linux does with the EC in these two cases, and hopefully that gives us some insight on the best solution. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2088733 Title: low CPU frequency after wake up AMD Ryzen Status in Linux: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: After wake up I can see at least once a week issue with CPU frequency not going up. When running: $ watch lscpu -e=CPU,MHZ standard output looks like: CPU MHZ 0 400.0000 1 1383.2480 2 400.0000 3 400.0000 4 400.0000 5 2699.7561 6 1288.0500 7 400.0000 8 400.0000 9 400.0000 10 400.0000 11 400.0000 12 3244.0720 13 400.0000 14 400.0000 15 1295.9050 while when the issue occurs, I can't see 600 Mhz or higher values in the same graph. Which also means that response time of computer is much lower and everything feels lazy. Restart fixes the issue or plug power cable off and in again.
