For the most part my Linux benchmarking of
Intel Broadwell systems currently in the form of the
ThinkPad X1 Carbon and
Intel Broadwell NUC have been going great. Major Linux distributions tested on this latest-generation Intel hardware have been going well, but the first major failure I've run into on Broadwell was when firing up
Mageia 5 Beta 3.
In trying to decide what new Broadwell Linux tests to run, I decided on a large Linux distribution comparison using the Intel BOXNUC5I3RYH with Core i3 5010U processor and HD Graphics 5500. When booting up Mageia 5 Beta 3 x86_64 this morning was the first time I experienced show-stopping failure of Linux on this NUC, where as Ubuntu and Fedora were running fine:
By default it's an unusable experience with the mode-setting having experienced a catastrophic failure.
It seems to be an issue with Mageia's Intel DDX driver as when switching over to a VT console the screen is rendered correctly. Mageia 5 is using the Linux 3.19 kernel, Mesa 10.4, and X.Org Server 1.16.4.
I haven't yet seen if there's other Intel non-Broadwell systems running into this issue with Mageia 5, but anyhow, it looks like Mageia is being left out of this forthcoming Broadwell Linux distribution comparison.
