(Not that the = simple=20 > boot + kernel build test that -tip does would have uncovered this particu= lar bug.) Some time ago, Tony Lindgren asked me to test Nokia N900 on -next from time to time. I do, and it uncovers problems from time to time. Perhaps if Linus or you asks for a volunteer, they can get one? We have people submitting patches due to various challenges, perhaps "run -next for a month" would be suitable challenge?
