Thank you for the report. The block size for this test is 1 KB, so I suspect this is the issue with insufficient journal credits that we are going to resolve.
I have applied your patch set [1] and tested and the reported regressions did not fix. Am I missing anything ?

I can also reproduce the similar warning with xfstests generic/730 under 64k page size + 4k block size.
Thanks, Joseph
