i've installed today the new intrepid ubuntu, since then I've experienced 4 freezes all caused by the same factor (or so it seems), all of them required hard boots.
here is the message from the system log from the last freeze:
all of the other freezes had the same entry. it seems that the cause of the freezes is pulse audio, so i've removed pulse audio, but the freezes still continue with the same message.
Oct 31 13:41:11 my-ubunutu pulseaudio: main.c sterlimit(RLIMIT_NICE, (31, 31)) failed: Operation not permitted
Oct 31 13:41:11 my-ubunutu pulseaudio: main.c sterlimit(RLIMIT_RTPRIO, (9, 9)) failed: Operation not permitted
what else can i do????
if I may add, I've experienced freezes with ubuntu hardy and gusty but the reason was my graphics card not the audio engine.
