Yes. It would appear that the fix/config change was not rolled into 5.4.0-33-generic. RT_GROUP_SCHED is still enabled in generic build but not lowlatency kernel build.
twiggy@twiggy:/ $ zgrep CONFIG_RT_GROUP_SCHED /boot/config-5.4.0-33-generic CONFIG_RT_GROUP_SCHED=y twiggy@twiggy:/ $ zgrep CONFIG_RT_GROUP_SCHED /boot/config-5.4.0-33-lowlatency # CONFIG_RT_GROUP_SCHED is not set I have no idea why... so still using lowlatency build here for now. ymmv! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1875665 Title: rtkit-daemon[*]: Failed to make ourselves RT: Operation not permitted after upgrade to 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1875665/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
