Comment 38 for bug 290498

I have been testing a couple of nights and it happened everytime I had done a Jaunty update. I could pretty well be a motherboard related issue because my suspicion was pointing to the acpid tools. so what I did is :

1. install 9.04
2. install wicd wireless network tool (skip this when you don´t need it) +reboot
3. removal of acpid and dependencies +reboot
4. jaunty update + reboot
5. install of both new ubuntu based RT kernel + reboot:

Files for everyone to use (at own risk) can be found at:

5. changed audio settings

sudo gedit /etc/security/limits.conf

at the end of file:

@audio - rtprio 99
@audio - memlock unlimted
@audio - nice -19

And voila no problem anymore, a perfected running pc.

I did a reboot almost after every installation action because I wanted to know if the sound modules were still in working condition after I had done the installs.

Again the not shutting down issue and sound getting killed could have been a local issue with my pc, but at least what I can do is share this information with you.

Realtime dutchman.
