Can those experiencing this issue try the following kernel boot option (& un-blacklist any previously blacklisted drivers): nohz=off

This may solve the issue. -- ksoftirqd/1 using 50% CPU or above https://bugs.launchpad.net/bugs/183461 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
