This will tell us whether the problem is format-specific or not. Also, are you able to use OpenCL on this system from any other program? > >../run/john --test --format=wpapsk-opencl --device=0 We've recently (shortly before the 1.9.0-jumbo-1 release) switched to 1-based device numbering, so there's no device 0 anymore. > > I see > >Device 0@...i: Mali-T860 > >Benchmarking: wpapsk-opencl, WPA/WPA2/PMF/PMKID PSK [PBKDF2-SHA1 > >OpenCL]...

In fact, the mention of "ASIMD" suggests it was with a revision very close to 1.9.0-jumbo-1 even if not the release exactly. (We sort of mistakenly reported Aarch64's SIMD as NEON before.) Alexander
