Experiencing hangs since last update

[rmetrich]

Hello,

since last system update (linux 3.6.11-16-ARCH+), I'm experiencing hangs of a few seconds of the RaspberryPi appearing every couple of minutes, although system is idle.
I suspect this behaviour is quite new but I'm not 100% sure.

Is anybody experiencing such issue ?

Example of hang, recorded using a shell script:
$this->bbcode_second_pass_code('', '

Hang for 6 seconds at Wed Aug 28 14:44:42 CEST 2013
Hang for 5 seconds at Wed Aug 28 14:45:09 CEST 2013
