Yes, We've got plenty test results for kernel that contains fd74da217df7d such as v4.9, v4.10-rc1, v4.10-rc2...., they all have the same dmesg errors. For the incomplete run, it may happen sometimes due to kernel panic during boot time and 0day failed to capture its dmesg stat.

This "dmesg stat is empty" refer to test for kernel image which head commit is fd74da217df7d, not for all test results.

Yes, currently we just found this issue on a specific machine, and I've queued the same jobs to other machines to see whether they have the same issue.
