I haven't used mdadm, and don't have it installed at this time, but, as best I can recollect, it's in the mdadm manual page. It's --zero, I don't remember well at all.

After finding the appropriate page on the Asus site (which Asus went out of their way to hide) and downloading and flashing the up to date BIOS, my PC started working. By working, I mean that I could use both RAM sticks without the BIOS program hanging, and the Gentoo minimal CD would actually boot. :-) Well, I had to prise a "standard" backing plate of the motherboard with a screwdriver, because some intelligent person had decided to glue it on. (By backing plate, I mean the metal plate which supports the weight of the processor cooler.) All in all, the MB I bought wasn't of merchantable quality. I hope it is, now. I've got 90% through a Gentoo installation on it, and I'm just considering how best to un-mdadm my boot partition (which I mistakenly turned into a RAID partition with its partner on the other drive). I can't erase the mdadm metadata stuff with mkfs.ext4 (even with the "force" parameter), and I don't think mdadm provides a method for undoing RAID. I can see myself having to use dd from /dev/zero to be able to get my partitions back again. Or can grub2 handle RAID partitions? This is the first time I've ever used grub2. But the installation kernel is 4.9.16. I've not noticed (yet) anything failing to work which I would expect to work. Once I've got my own kernel up and running, I'll start looking at 4.10.x. > Alan Mackenzie wrote: > > > >> He [Alan Grimes] has new hardware (Ryzen) that needs 4.10 for proper > >> support. > > I too have new hardware (An Asus Prime X370-PRO MB with a Ryzen 1700X > > processor), indeed so new that my first attempt to boot a minimal CD was > > less than an hour ago. > > > -- > Strange Game. > The only winning move is not to play. > Powers are not rights. -- Alan Mackenzie (Nuremberg, Germany).

On these new mobos, it's important to update the BIOS as soon as possible. I DL'd a Bios with my 'doze 7 machine first thing and flashed it. The original bios I had was version 418 from February, the new one was 520 from a few days before I started... It is very important this is done before anything else is attempted with the system.

If 4.10 is necessary, is it sufficient? I've been doing a lot of research on Ryzen as I was considering an upgrade myself. 4.9 has some support, so it should boot at least. From what I read only 4.10 has full support. Do be aware that there was a show-stopper bug in firmware[1] that was causing hangs and lockups, have you upgraded your motherboard firmware? I figured I'd wait another six months before committing to the thought of any upgrade to give AMD time to sort the chips out. I myself was eyeballing the 1700X or 1800X processor. You might be better off booting a systemrescuecd or something like a Mint CD. I flip-flop between the two of them.

I can't recall when was the last time I used a Gentoo minimal CD to install a
system and I have not tried installing Gentoo on Ryzen (yet), but have you had
a go at using a systemrescuecd?
You'll need to use the alternative kernel from the boot options, which is at
present still a 4.9.18 version:
http://www.system-rescue-cd.org/Download/
Alternatively, you can unpack it, build the kernel of your choice and rebuild
it as explained here:
http://www.system-rescue-cd.org/Customization/
The same must be doable with Gentoo's minimal CD, but I have not searched the
interwebs for guidance ...
HTH.

I too have new hardware (An Asus Prime X370-PRO MB with a Ryzen 1700X
processor), indeed so new that my first attempt to boot a minimal CD was
less than an hour ago.
The attempt, one must admit, was wholly unsuccessful. I can boot into
the minimal CD's opening overtures, at which I'm prompted to select a
"kernel". If I choose memtest86, it loads and displays its initial
screen, then promptly crashes the system, leading to an automatic
reboot. gentoo-nofb boots, displays something about the number of cores
present (It counts up to #16), displays some information about "PCI"
(on, perhaps, 20 lines) and promptly crashes, blanking the screen and
rebooting.
My minimal CD is install-amd64-minimal-20170406.iso, so fairly recent,
but built with kernel 4.9.16.
Question: do I need a 4.10 kernel to be able to boot a Ryzen system at
all? If 4.10 is necessary, is it sufficient?
Just as importantly, are there any convenient instructions in a
convenient place for building one's own minimal CD? I've just tried a
quick search through the Gentoo wiki, but didn't see anything relevant.
Is there anything else relevant anybody can tell me to help me get my
new machine booted?
Thanks in advance!
