the error log
Just randomly checked dmesg and this appeared, so I followed the encouragemente to file a bug.
No anomalies in system.
Using Gentoo in a Lenovo Yoga 2 11 (it has bay trail if i remember correctly)
No obvious sign of corruption in the ring state. The next step would be to dig into the 3d state and work back from there.
