[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 vadaszi.

Category set to Kernel

The

uhub0: <0x8086 XHCI root HUB, class 9/0, rev 3.00/1.00, addr 1> on usbus0

shows that the xHCI controller was apparently recognized.
Since DragonFly isn't finding any storage device, it could be that the kernel just isn't waiting long enough for the USB stick to be recognized.

You can try setting the vfs.root.wakedelay tunable (as also mentioned in the loader(8) manpage) in the bootloader prompt, to wait for e.g. 10 seconds before it tries to mount the root filesystem:

set vfs.root.wakedelay=10

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.

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
