Shader triggering the endless loop
I think the last log was not correct, i.e. it was not the right shader. This
new log shows different error messages. The the endless loop is happening in
"post_scheduler".
I've run the code with R600_DEBUG=nocw,sbdump in addition to the PSC_DUMP.
I've also tried R600_DEBUG=sbsafemath, but to no avail.
Snip of the log:
