Oh I see.  The 2.6.22rc1-git5 has new reset sequencing which uses
deadline table so it takes 10sec to fail to first reset try while 2.6.21
needs 30secs.  That's where the 20sec difference per each try comes
from, so newer version is better.  Great.

Hmmm... It doesn't like SETXFERMASK either.  Please try the attached patch.
