Comment 1 Jianxun Zhang 2016-01-26 22:55:30 UTC 
I don't have NUC now to repeat this issue, need to find some way to reproduce it.
Comment 2 Jianxun Zhang 2016-02-11 22:28:08 UTC 
I have to assign this back to reporter for more information. Now I have got NUC gen 6 but cannot reproduce two errors in log attached.


For this DRM error:

"Central error: [    0.463667] [drm:__gen6_gt_force_wake_mt_get] *ERROR* Timed out"

My NUC gen 6 has new issues with graphic in UEFI boot with genericx86_64 build (minimal and lsb). So I tested it in legacy boot mode. Cannot reproduce this error. Please reporter let us know:
() If this issue can still be seen in NUC you have
() model info of impacted NUC device if issue is still there.

For another uvesafb issue,
" uvesafb: Getting VBE info block failed "
This issue is same as https://bugzilla.yoctoproject.org/show_bug.cgi?id=6584. The fix has been back ported to Jethro from master, so I don't think this error still effective.

Cristina,
If you still see the first DRM error with recent builds on that NUC, please help to provide the necessary info and feel free to assign it bake to me.

Thanks lot!

On jethro 2.0.1_rc6, poky: 5b12268f6e17574999f91628a60e21711cf62ee4 core-image-sato-sdk the issue cannot be reproduced. Since the error is no longer present we could close it and reopen if needed.
Comment 4 Cristina Agurida 2016-02-15 15:44:13 UTC 
Set it as verified.
