From: Linus Torvalds on 21 Jan 2010 18:50 Hmm. I don't think there is anything earth-shaking here, although the i915 KMS changes might be noticeable. Notably if you have eDP ("embedded DisplayPort" - I think mainly a feature you'd find on a new imac), in which case it now hopefully works, but more commonly if you saw the flickering on your laptop panel due to LVDS downclocking (which saves power, but is now disabled by default until that thing is resolved). And there's a new DVB "Mantis" driver there. Other than that, it's a lot of random fixes, mostly small. And some defconfig updates, mostly huge and totally boring.

After suspend, the right monitor shows very funny colors, as if it is on crack, in contrast to the left one which looks fine: http://userweb.kernel.org/~bp/right_monitor.jpg http://userweb.kernel.org/~bp/left_monitor.jpg This started to appear after .33-rc4 and it could be a KMS-related glitch since switching to one of the text terminals with <CTRL>+<ALT>+<F1> and back to X seems to fix it. Ccing relevant parties. 2. During suspend I get this juicy lockdep warning: [ 52.549427] PM: Syncing filesystems ... done. [ 52.611462] Freezing user space processes ... (elapsed 0.01 seconds) done.

You didn't say what GPU you have, but judging by your CC list, it's a radeon. You might want to let the Radeon KMS people know exactly what your setup is etc. > 2. During suspend I get this juicy lockdep warning: I'm pretty sure that this is not actually a new problem, it's a new warning for an old problem, see commit 846f99749 ("sysfs: Add lockdep annotations for the sysfs active reference"). So I'm not considering it a regression, even though I do agree that the messages look scary and very annoying. I'm not at all convinced that we are going to be able to fix the problems that this made visible in time for 2.6.33. The sysfs-related lock chains easily get rather involved, although it is always possible that this particular one might be easily fixable (ie if radeon is able to call the final kref_put outside any locks - or whatever it is that ends up generating a dependency from struct_mutex for the sysfs active ref). Or maybe I'm misreading the lockdep chain. Eric Biederman added to cc.

If you want to use KMS, use the radeon driver (xf86-video-ati), otherwise, disabled KMS.
