Do you still experience this problem with recent FreeBSD versions?  Note that DRM support had moved out of the base system/kernel to the `graphics/drm-*-kmod' and `graphics/gpu-firmware-kmod' ports.

Your report was against 11.0-STABLE which is no longer supported.  Please update to contemporary, supported FreeBSD version and reconduct your tests.

Adding x11@ to CC list so it can be tracked while originally filed under base system/kern.

I've been running the vesa driver ever since, I will try again but I believe it still panics with non KMS capable amd/ati video cards. I'll confirm with 12.2 when I get the machine updated.

12.2-STABLE still kernel panics when trying to startx with a non KMS capable AMD/ATI video card.

Non-KMS capable hardware isn't really supported any more.
