The summary of my tests says: Build results: total: 151 pass: 130 fail: 21 Qemu test results: total: 430 pass: 375 fail: 55 sparc32 smp images in next-20200603 still crash for me with a spinlock recursion. s390 images hang early in boot. Several others (alpha, arm64, various ppc) don't even compile. I can run some more bisects over time, but this is becoming a full-time job :-(.
