Is there any (target specific) testcase you can add? Such commits are
problematic
when later bisected to since the intent isn't clear.
I made a issue in bugzilla, please check it, thanks.

So what Richi is asking is can you construct a testcase for the
testsuite? Having a BZ is helpful because we can reference it in the
commit message, but a test, even if it's target specific, is even better
from a long term maintenance standpoint.
