I am testing it under two configurations with Karmic i386: Sony Vaio
Centrino laptop, and AMD dual core workstation. It is quite stable (I
have no problem even at very low latency), real time with jack works
like with -rt kernel. Could it be possible to have a -headers for this
kernel, in order to test the closed graphic drivers, before to report to
kernel team ?
