Sep 25 22:06:34 mutilate warning: : [ 544.721415] radeon 0000:01:00.0: vbo resource seems too big for the bo followed by a massive stream of "vbo resource seems too big for the bo". The most extreme flood ran from 23:01:58 to 23:02:47 and emitted 91,000 lines of log in that time. This... seems excessive, given that each log message after the first contains more or less no information. So ratelimit these messages. (We probably want to see at least *some* so that the underlying bug can be fixed -- always assuming the bug isn't in unfixable closed-source game code somewhere.)
