Unfortunately, they are too intermittent to tell if it is a regression, and more importantly, it would be a bitch to bisect the code as one would need many weeks of testing before saying that a particular kernel was good. When I first got 64-bit dma working on a BCM4311/2, there was always one such error. That was removed when Michael changed the dma code. Now I do not get any on most runs, but every once in a while (3 times since July!), I get a storm of these. Unlike most of you, I have seen the Broadcom code. There is almost no error checking in their routines, which is good for us - it makes the code smaller and the decompilation easier. I will never RE the binary blob of the hybrid driver for a number of reasons; however, I doubt that their culture has changed. As to why their driver has such poor performance, your guess is as good as mine.
