I see 'no active waves' print meaning it's not shader hang.

We can try and estimate around which commands the hang occurred - in 
addition to what you already print please also dump

sudo umr -O many,bits  -r *.*.mmGRBM_STATUS* && sudo umr -O many,bits  
-r *.*.mmCP_EOP_* && sudo umr -O many,bits -r *.*.mmCP_PFP_HEADER_DUMP 
&& sudo umr -O many,bits  -r *.*.mmCP_ME_HEADER_DUMP
