Hi Bill,
This is not the result of a recent change to the serial driver. I don't
know how far back this bug goes, but I suspect it is as old as the proc
fs serial support.
The recent event was me adding memory mapped support for a couple of
CompactPCI serial mux cards. Apparently everyone else on the planet
uses I/O space (or just did not report it) and the driver/kudzu
combination works fine with serial cards in I/O space.
Do you want me to go ahead and put it into bugzilla?
BTW, I have attached the procfs data produced with and without the
driver bug.
Best regards,
Ed Vance
