   > @tkonolige I tested it, and had the same behavior. I was able to get better error messages by changing [this line](https://github.com/Lunderberg/tvm/blob/main/src/meta_schedule/utils.h#L292) from `tir::ScheduleErrorRenderLevel::kNone` to `tir::ScheduleErrorRenderLevel::kDetail`, and it looks like the error is thrown from [this check](https://github.com/apache/tvm/blob/main/src/tir/schedule/primitive/for_kind.cc#L160) when trying to parallelize the function. That's as far as I got from now, without digging too much into the meta scheduler.
   
   This is indeed an orthogonal but serious problem. @tkonolige  would you like to create a separate issue and bisect to determine which commit causes this bug?
