I'm not sure this is an important warning or not. But after this warning, kernel is proceeding its initiation anyway.
2) The second issue is: domU's ubuntu desktop is not properly working. Just the background screen shows up and I can move mouse pointers. But, nothing happens afterward. So, I uninstall ubuntu desktop and install xubuntu desktop. And Xubuntu desktop looks working for me.
3) In Xubuntu desktop, I tried to run glxgears (very simple opengl application), but it gives this message and failed.
glxgears: brw_vs.c:138: brw_compute_vue_map: Assertion `!"VUE map not known for this chip generation"' failed.
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
I'm willing to take a deeper look, and appreciate if you tell me some comments or pointers.
Hello,
I picked up the baytrail patch in the repository and tried to run it on Asus T100 (BayTrail) and encountered 3 issues:
1) In the domU booting phase, it shows a kernel warning:
