Control: severity -1 serious
I have been working on this upstream:
https://bugs.freedesktop.org/show_bug.cgi?id=100639
It appears to totally break beignet on Ivybridge/Haswell on recent
(including sid/stretch) Linux. (I didn't notice it before because I
test in a chroot, i.e. with jessie's too-old-to-be-affected Linux.)
It's not yet entirely clear what to do about it:
The above patch works for me, but apparently not for everyone.
The other known partial fix is to disable softpin, but that also isn't a
complete fix, and also disables OpenCL 2.0.
