It seems there's problem with alsa and pulsaudio (less) but some people working on it and submit several patch: http://article.gmane.org/gmane.linux.alsa.devel/106927/match=schiit or http://www.spinics.net/linux/fedora/alsa-user/index.html#11854 dmesg output before reboot : # dmesg Linux version 2.6.26.8-rt16-332-g5849bfa (adrian@ubuntu) (gcc version 4.4.1 (Sourcery G++ Lite 2010q1-202) ) #999[usb] PREEMPT RT Wed May 2 20:14:28 BST 2012 CPU: ARMv6-compatible processor [4117b363] revision 3 (ARMv6TEJ), cr=00c5387f Machine: Logitech Fab4 Board ...truncated...
