[DragonFlyBSD - Bug #2890] not able to boot usb installer on Toshiba Chromebook 2

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #2890 has been updated by johnnywhishbone.

Target version changed from 4.2.x to Unverifiable

The xHCI (EHCI) controller seems to be not recognized, when the kernel loads. Every of the other BSDs seems to have no driver for the Bay Trail xHCI controller. Googling "xhci bay trail" it spits out a lot of bug repots and commits for several linux distros who solved the problem. I also found the data sheet for the controller (http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/atom-z36xxx-z37xxx-datasheet-vol-1.pdf) but lacking the skills to program it myself :-(

Hello,

i am not able to boot DragonFlyBSD 4.4.1 on a Toshiba Chromebook 2 (CB30-B-104, BayTrail device, Coreboot/SeaBIOS {after patching https://johnlewis.ie/custom-chromebook-firmware/rom-download/  }).
First i thought it is Coreboot/SeaBIOS-related, so i started a thread in the mailinglist: http://www.seabios.org/pipermail/seabios/2016-February/010485.html

The kernel is not able to find the usb stick or an sd card. No da*-devices are present.

dmesg (Arch Linux): http://pastebin.com/FNEhYdsZ
lspci -v (Arch Linux): http://pastebin.com/pnFErXqG
Coreboot-log (cbmem): http://pastebin.com/asLqar5q

Linux is running well (after some tweaking) since it is the base of ChromeOS. But none of the BSDs. Even the most recent snapshots (i tested amd64 and i386 on usb stick and sd card) from OpenBSD, NetBSD, FreeBSD and DragonFly won’t boot. They all stop at the same point and try to find the root-device.

Please let me know if i can provide more information about the machine.


Thank you very much!
Best greetings,
— Ronny Schneider
