it87 with 2.6.33.2: noise
With 2.6.33.2, as soon as it87 is loaded, my speaker (or something I couldn't identify) starts like an alarm/ring and doesn't stop until I reboot. It didn't happen with 2.6.32.

[PATCH 0/4 v3] ext3/4: enhance fsync performance when using CFQ
Hi, The previous two postings can be found here: http://lkml.org/lkml/2010/4/1/344 and here: http://lkml.org/lkml/2010/4/7/325 The basic problem is that, when running iozone on smallish files (up to 8MB in size) and including fsync in the timings, deadline outperforms CFQ by a factor of about 5 for 64KB ... 14 Apr 2010 17:48

[PATCH 2/3] perf: Always record tracepoints raw samples from perf record
Trace events are mostly used for tracing rather than simple counting. Don't bother anymore with adding -R when using them, just record raw samples of trace events every time.

[PATCH 3/3] perf: Make the trace events sample period default to 1
Trace events are mostly used for tracing and then require not to be lost when possible. As opposite to hardware events that really require to trigger after a given sample period, trace events mostly need to trigger everytime. It is a frustrating experience to trace with perf and realize we lost a lot of events b... 14 Apr 2010 17:47
