Have a bit more information now:

By the update I moved from mesa 17.1.7 -> 17.3.7.

I git diff'ed  around a bit:

* Tiling was introduced (or just reworked?)
* the error message is created in vc4_resource_from_handle. The handle
coming in has modifier DRM_FORMAT_MOD_LINEAR (0x) but kernel says 'hey
I support tiling' DRM_FORMAT_MOD_BROADCOM_VC4_T_TILED
(0x7000000000000001) [1].

With this I'll try some hacks and then ask at mesa mailing list what
might be reason for it (a really bad timing for this...)

Cheers
