Sundtek Support Forum

Since the installation of the Sundtek device with the Net-Installer I have kernel-panics occasionally on my Intel NUC D34010WYKH (Intel i3).

I'm beginning to suspect there is something 'wrong' with the USB3-implementation on Linux on the device, since I would expect the Sundtek-drivers being userspace-drivers they alone can not cause kernel-panics... However, I must say that it only happened after I connected the Sundtek USB-stick and "the taint is on mediasrv" which is from the Sundtek-drivers.

I was wondering if any of you guys can shine some light on my issue, hence a copy/paste of the stack-trace after a recent kernel-panic:

This is taken on Ubuntu 14.04 - it happened on both the supplied 3.13 kernel as well on the 3.14.1 kernel which is installed right now.

Unfortunately the device has only USB3-ports connected on the outside and I can not seem to find a way to 'fall back' on EHCI rather than XCHI - but perhaps you can shine a light on this ?

To clarify, it is this device:
http://www.intel.nl/content/www/nl/nl/nuc/nuc-kit-d34010wykh.html

I have BIOS 0025 installed on it (latest stable) and Ubuntu 14.04 with kernel 3.14.1 (Linux 3.14.1-031401-generic #201404141220 SMP Mon Apr 14 16:21:48 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux)
