For my part, all I can say is that -next is in pretty bad shape right now.
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 :-(.
