btw, you may want to see the IDE_TCQ_FIDDLE_SI define in ide-tcq, here's the comment I put there:
/* * we are leaving the SERVICE interrupt alone, IBM drives have it * on per default and it can't be turned off. Doesn't matter, this * is the sane config. */ #undef IDE_TCQ_FIDDLE_SI
Are you sure this isn't what you are seeing?
