Announcing the Linux Kernel 4.2 RC3 release, Linus Torvalds wrote:
“Normal Sunday release schedule, and a fairly normal rc release,” says Linus Torvalds. “There was some fallout from the x86 FPU cleanups, but that only hit CPU’s with the xsaves instruction, and it should be all good now. […] I’d have liked rc3 to be slightly smaller than it is, but I don’t think there’s anything _particularly_ scary going on.”
Note: Before installing Linux Kernel 4.2 RC3, please note down the system’s architecture (i386 debs for 32 bit systems and amd64 debs for 64 bit systems).
