No, we can add said preliminary fix to the F9 (and earlier) kernels. In fact, I'm inclined to add the OHCI 1.1 iidc fixes from David Moore to rawhide later today, as well as port them to the 1.0 code (which I'd also include). > _and_ firewire audio interfaces as well. > > Which forced me and others to return to the original stack in my > realtime tuned kernels for Planet CCRMA.

It works quite well where it does work -- sbp2 devices and dv capture. In the sbp2 case, it works far better than the old stack ever did. We're just a bit lacking in man power to fix up the broken things. Rather than spend time working on fixing the new stack, people run back to the old stack. Of course, I understand some people need things to be working NOW, but there's a chicken and egg problem there. I don't do any firewire audio stuff, so offhand, I don't have a clue how to fix the particular problems you're seeing (I'm not even sure *what* the problems are). The things I do (sbp2 storage and dv capture) pretty much Just Work -- and dv capture only does so on (most) OHCI 1.0 controllers, because I sat down and wrote the OCHI 1.0 isochronous receive support code (with lots of help from krh, mind you, since I knew nothing about the code going in). > My opinion is that the new stack was not and still is not ready for > inclusion in a mainstream distro.

Yeah, I'm part of the chorus. > But > it has been shipped for a long time and not fixed so I _don't_ buy that > argument. Admittedly, we've been rather slow to fix things, so I do understand your not agreeing with the chorus. :) But things *are* improving, and we *do* intend on continuing to fix things. We're just a bit short on man-power to actually sit down, reproduce problems, debug and fix them. I only recently got familiar with the kernel code myself, and my day job deals mainly with RHEL kernel stuff, but I'm quite happy to try to help out with any Fedora firewire bugs still outstanding (several are already on my plate). If you have any open bugs, or want to file any new ones, please do. Assign them to me (jwilson@xxxxxxxxxx) and cc Kristian (krh@xxxxxxxxxx) and Jay (fenlason@xxxxxxxxxx). > Agreed...
