Do you know if that was an regression in libdrm and if that patch might also fix #26294 [1]? DebPkg:libdrm2 was upgraded during that time from 2.4.14 too.
Unfortunately I do not know how to rebuild that package with the patch applied and to test it. If you know a live CD having this patch applied I could test it though.
Thanks,
Paul
