@scchan If I understand your message correctly. There are 24 failure with LC, and 0 with HSAIL, right?

[scchan]

there were no failure on hsail

I turned off activelaneid and activelanepermute for now.

this would make this test fail even on HSAIL backend. it's better to use hcc_backend macro to check. I'll fix it. the same goes to activelanepermute right below.
