this is caused by enabling softpin in mesa, which is supported in kernel 4.5 and up but is still somewhat buggy as seen here.. we need these commits backported to the kernel:

9125963a9494253fa5a29cc1b4169885d2be7042 drm/i915: Mark up GTT sizes as u64
6fc4e48f9ed46e9adff236a0c350074aafa3b7fa drm/i915: Compare user's 64b GTT offset even on 32b

but since 18.04.2 is about to be released, it's best to revert enabling softpin in mesa, and enable it again for 18.04.3.
