So I'm assigning this to him and see if he grumbles :-). He can always assign it away if he's not interested in commenting on the API change. But I wouldn't overstate the problem, as far I can tell this will only happen with certain designs of devices, and only then if certain situations combine, which therefore makes it uncommon. That's not to say it's irrelevant, but it's not like it happens every interrupt or anything like that. -- Configure bugmail: http://bugs.ecos.sourceware.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
