That has fixed this issue - nice perf boost with your latest commits :-)

Unfortunately after running for a while I managed to trigger the issue I 
previously reported.

It only took 10 mins - after the fix following the last report I ran for 
an hour and then next day 45 mins without triggering it.

r600_pipe.h:743:r600_write_context_reg_seq: Assertion `cs->cdw+2+num <= 
(16 * 1024)' failed.
double fault: 'Trace/breakpoint trap', bailing out
