Could unwrap this line now.

Maybe improve the English on this one? "Received 'no space for error 
capture' notification"? Or maybe just "No space for error capture"? I 
don't think you can get a similar error from anywhere on the i915 side.

Again, redundant 'GuC' string. Also, maybe drop the 'request' given that 
this is a GuC generated reset not a reset request from i915. This 
message has resulted in confused bug reports in the past. So, maybe go 
with just "Engine reset failed on ...".
