The Linux 4.7 Kernel Builds Are Finally Playing Nicely Again On All My Systems

Nearly two weeks ago I warned that You May Want To Think Twice About Trying Linux 4.7 Git Right Now. Fortunately, all is well now and those problems have cleared up.

With the early Linux 4.7 kernel builds at least from the Ubuntu Mainline Kernel PPA, on all my x86 Linux Git systems there were "error getting socket: Address family not supported by protocol, error initializing udev control socket" messages followed by dropping down to BusyBox. It happened on the systems I benchmark daily and it seems many other individuals trying out Linux 4.7 also hit this problem.

Fortunately, as of yesterday (or the Git that landed since Friday morning) seems to take care of these problems. Yesterday my benchmark systems were successfully running with the latest daily packages via the Ubuntu Mainline Kernel PPA without any problems.

Linux 4.7 has many new features so if you want to give the development kernel a go on your Ubuntu-based system, you can do so via these packages. The daily benchmarks of the Linux kernel can now continue on
