To be fair they have caught and fixed some things like the timer bugs that John found, it's just that none of them have been boot breaks thus far.
Yeah, but the boot and build breakages should be much easier to find, one would think :)
Sort of. They do tend to be quite easy to detect if you're running the right boot test but we've acquired rather a lot of different options in our boot paths (even excluding all the possible driver combinations) so getting the coverage there isn't as trivial as you might hope. kernelci regularly finds boot problems that only manifest on some small subset of boards or subset of boot methods.
The LKFT people can correct me if I'm wrong here but my understanding is that they're focusing more on improving coverage of things beyond boot than on the basic boot stuff given that there's other stuff like kernelci and Olof's build farm out there covering boot, boot does benefit from having a big broad set of boards to test on and LKFT doesn't have that.
