I had Kernel 3.19.0<\/strong> (originally from https:\/\/github.com\/raspberrypi\/linux\/tree\/rpi-3.19.y<\/a> – now updated) running on my Pi (armv6) and Pi2 (armv7) with no problems (apart from the Pi2 seeming very<\/span> sluggish..) but after that had a few ‘issues’..<\/p>\n

Pi:\u00a0 Kernel 3.19.1 OK, but 3.19.2 refused to boot (nothing on console)<\/p>\n

Pi2:\u00a0 Kernel 3.19.1 booted and then crashed:<\/p>\n

Pi2 with Kernel 3.19.2 had the same result as the Pi – no boot, and blank console..<\/p>\n
It seems that the git repository contents are often updated, but the version is still the same, which makes tracking updates tricky!\u00a0\u00a0\u00a0\u00a0 This means that the ‘3.19.2’ I download today may well be different from the ‘3.19.2’ I downloaded a few days ago..\u00a0\u00a0 I know that this can all be controlled by git, but it it might be better for the average user if the ‘extraversion’ was used to signify fix levels, without resorting to git command complexity to control all this..<\/p>\n
