No, I didn't say this. The first time I didn't even try, because our
software uses the persistent names, not /dev/ttyR*, but the udev
rename rules didn't fire. So I fixed the rules, removed and
reinserted the module, then started the console multiplexer, which
provoked the bugs (all 16). I don't think it has anything to do with
the issue, but wanted to explain the "last removed: rocket" part of
the log.

Looks like Jiri has a handle on the problem, though. Once you
converge on a patch and need testing, tell me. I'm not in a hurry,
the current Debian stable kernel works OK, I tested 2.6.29 while
investigating an unrelated networking issue.
