Hi all,

Two things:
- Please _always_ include a public mailing list when reporting bugs, your
dear maintainer sometimes slacks off.
- We need to see the error_state before we can assess what kind of hang you
have (it's like gettting a SIGSEGV for a normal program, no two gpu hangs
are the same ...).

Cheers, Daniel
