Is this correct? No, the second argument of git-clone is the destination directory to clone, not the branch to pick up. The cloned repo has all branches but doesn't point mm branch.

This was already reverted (based on your report) on git. > If I replace "udelay(10)" > by "udelay(500)" in the original rc7, then there is still no sound. Interesting... What about udelay(1000)? Then it'll be closer to msleep(1). > This is like fishing in the dark. We've got a working version. Why not > keep it? Yes, we are shooting in the dark now indeed. Honestly, I have no concrete idea why the patch breaks the sound initialization. It seems that Dell machines (or STAC codecs) have problems with the initialization timing. I don't think that all commands but only certain some command sequences that are so sensitive to the access timing. We need to identify this. Ingo's patch is basically a really nice fix. It reduces the unnecessary delay, especially improves resume speed much. I'd love to have it. And above all, I need to understand what is the real problem. Unfortunately, I have no this hardware and the precise h/w data, so must rely on testers and a guess work. thanks, Takashi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Maybe you could send me a pointer? The "regression" was your original problem, no sound on rc7, which was fixed by reverting the patch.

System itself is a Dell Inspiron 1420n laptop running a 64bit kernel and userland - there is a "pop" from the speakers when booting, but no sound at all. I'll pull a new tree from GIT, but I'm thinking that the above changes are probably related to the move from ACPI motherboard drivers to the PNP platform driver. What I don't understand is how, if there are only more mem resources than the new PNP platform driver can handle, why there are also ioport ranges that could not be reserved. Additionally, with the same kernel, the iwlwifi driver appears to cause the new 802.11 code to crash. This doesn't stop the driver or cause any problems with the connection. I've been using the iwlwifi driver with 2.6.22 for a while and haven't seen anything like this.

Hm... Just to be sure, try the patch below. It's a clean up patch that I'd like to apply later. The perex/alsa.git mm branch on kernel.org has many fixes.
