[Bug 1821441] Re: Clocksource changes from TSC to HPET after sleep. Kills performance.
I'm seeing the same thing. Basically, any use of clock_gettime now requires a syscall (isntead of using vsdo). The applications I'm running do a lot of clock_gettime's, and basically cannot run performantly anymore after this happens.

[Bug 1773959] Re: High CPU usage by gnome-shell when only running gnome-terminal
Expanding on Shambler's 2019/03/23 comment, clock_gettime showing up in the strace can be caused by the TSC clock source being marked unstable (after a sleep for some people, like me). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773959 Title: High CPU usage by gnome-shell when only running gnome-terminal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1773959/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I was sent to this bug by the system software (crash reporter, I guess). I think I'm having a different issue. I don't have /boot on USB. My /boot is full (which I'm actively trying to clean up), but I'm guessing these are similar problems of "couldn't write to /boot". ** Changed in: grub2 (Ubuntu) Status: Invalid => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1455383 Title: grub-pc 2.02~beta2-9ubuntu1.1 failed to install/upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1455383/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 874211] Re: mini-preview of minimized Google Chrome windows blank
Hi, I think I'm having the same problem, as well as another related one. 1) I see similar, but slightly different behavior with the preview: "Use system title bar and borders" *checked* -- preview broken sometimes. "Use system title bar and borders" *unchecked" -- preview broken sometimes. 2) The other problem: After being minimized, the window comes up all white except for the title bar. It doesn't re-render the screen until it's resized. This is really annoying, but I don't know if should be considered part of the same bug. There's another bug in Chromium that sounds somewhat like this, but maybe not exactly the same either (https://code.google.com/p/chromium/issues/detail?id=340138) "Use system title bar and borders" *checked* window restores as blank white window.

[Bug 1274456] Re: BOINC is always suspended, if set to work when IDLE
Hey, wow, Jussi, you have put in great effort trying to fix this! So I was just having this problem on Ubuntu 14.04.1LTS with boinc 7.2.42 and was disappointed to see how it doesn't look like this issue has been resolved. But, I think I just found a fix, and it'll need to bake a little longer to see if it really works. Basically, I installed xprintidle and restarted the boinc mgr and boinc client. Now, with it set to require 1 minute idling, it seems like it's working.
