Did you verify that reverting this commit or - if reverting is not possible - testing
out the revision just before the commit?
I did not yet revert the bad commit in a current kernel and test it, but
from my understanding the parent commit of the first bad one must have
been a good one and indeed, [67e306c6906137020267eb9bbdbc127034da3627]
is the parent of [028abd9222df0cf5855dab5014a5ebaf06f90565] and was
working for me on my T1000:

Just to be safe you found the correct commit.
If that has been verified, please report the issue to the sparclinux LKML and CC Christoph.
Will do that soon-ish but maybe also try to revert that commit in
Debian's 5.10.0-4 and test it for additional assurance (then not so
soon-ish - maybe this weekend). I'll put you and Riccardo in CC, too.
Hopefully this will be easier to fix than the kernel breakage on the
rx2800 i2 - assuming that problem is still there ([1], [2]).
