Hi Konstantin, It was not my intention to send this piece of code as a patch to be upstreamed. My apologies for that misunderstanding. My intention was just to send something for people to try and see if it solves the interrupt spam in their cards. I should have sent it just as a normal email to the list. You are right that I don't fully understand what those registers control because unfortunately there is no public documentation available (even for end of life products). But Andy Walls seem to have a very good explanation. I just disagree about knowing the author of this code... I had no clue it was you, all I knew is that it came from tbs under GPL. But if you say you are, I believe you and give you all the credit... To be honest I just want my tbs card to work as it should.
