2.6.35-rc{12} regression: inactive console corrupted
Hi! When something happens on inactive console (using fbcon), display is corrupted -- lines at end of screen are not erased properly. I see it on zaurus, but I suspect problem is generic. -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/ho... 22 Jun 2010 09:21

Unified NMI delayed call mechanism
* Huang Ying <ying.huang(a)intel.com> wrote: NMI can be triggered even when IRQ is masked. So it is not safe for NMI handler to call some functions. One solution is to delay the call via self interrupt, so that the delayed call can be done once the interrupt is enabled again. This has been implemented ... 19 Jun 2010 11:17

mpd client timeouts (bisected) 2.6.35-rc3
Commit 597a264b1a9c7e36d1728f677c66c5c1f7e3b837: �net: deliver skbs on inactive slaves to exact matches� causes large timeouts when mpd clients try to connect to a locally running mpd (music player demon) on my machine. This makes it impossible to control mpd. I bisected this down to the commit mentioned abov... 17 Jun 2010 12:18

[PATCH 2/5] perf: Support disable() after stop() on software events
If we call perf_event_stop() on a software event and then the disable() pmu callback on them after that, we'll call twice hlist_del_rcu() on the same hlist node and then bring a crash by dereferencing LIST_POISON2. Just use hlist_del_init_rcu() instead to fix this problem. This preparates for new context exclu... 12 Jun 2010 03:56

[PATCH 0/5 v3] perf events finer grained context instrumentation / context exclusion
Hi, In this new version, the weird hangs have been fixed. They were due to some ACTIVE state checks that didn't handle the paused mode. And also comes a new pmu->reserve callback to schedule an event on the cpu without actually starting it (as if ->stop() was just called in it). In x86 it is the same than th... 12 Jun 2010 03:56

[PATCH 1/5] perf: Provide a proper stop action for software events
In order to introduce new context exclusions, software events will have to eventually stop when needed. We'll want perf_event_stop() to act on every events. To achieve this, remove the stub stop/start pmu callbacks of software and tracepoint events that fixed a race in perf_adjust_period, and do an explicit chec... 12 Jun 2010 03:56
