Phoronix: Ubuntu Preparing Kernel Updates With IBRS/IBPB For Spectre Mitigation

Canonical has rolled out Spectre Variant One and Spectre Variant Two mitigation to their proposed repository with updated kernels for Ubuntu 14.04 LTS / 16.04 LTS / 17.10. These kernels with IBRS and IBPB added in will be sent down as stable release updates next week...

How looks performance drops on AMD platforms like Ryzen between IBRS/IBPB vs Reptoline? I'm afraid that due to crappy Intel's CPUs AMD users will notice much higher performance drop than required.

I think it's the ratio of middle managers to code monkeys... but anywho.

You'll be happy to hear that after literally HUNDREDS of users beotched about it, Ubuntu has decided to keep desktop icons in 18.04 Gnome. See how easy it was for the "community" to have a say in the matter? Not like pulling teeth at all.

Glad I don't work there.

I think they're glad you don't work there, either.
As am I...

AIUI, both Red Hat and SUSE had to pull the updates due to faulty microcode.
