Dear John,<br><br>On my machine i had a similar problem with rt. After more than 1,5 year of searching, trying out and lots of help with explanation on the ubuntuforums i discovered that it was this BIOS setting that must be turned off: IOAPIC It seems that ubuntu can manage this by itself(if i understood correctly) I bet this solves your problem too!<br> <br><div class="gmail_quote">2010/5/7 jONE <span dir="ltr"><<a href="mailto:producjohns@gmail.com">producjohns@gmail.com</a>></span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi Fernando I've got an AMD Athlon 64 X2 4000+ processor too and had problems with the RT kernel since I first installed 8.04 onwards. I tried pretty much everything until a few days ago, when I simply "loaded optimized settings" on my BIOS and believe it or not, no mouse delay and no hanging at all. My hammerfall soundcard's delay <10ms recording 16channels. I honestly don't know what setting in the BIOS messed it up since "optimized settings" or "default settings" options don't specify much and I've tweaked the thing so many times I lost track of what the original setting was! Maybe give that a try?<br> Good luck!<br><br>John<br><br><a href="http://www.silver-sounds.com/" target="_blank">www.silver-sounds.com</a> <div style="display: inline;"></div> <br>--<br> Ubuntu-Studio-users mailing list<br> <a href="mailto:Ubuntu-Studio-users@lists.ubuntu.com">Ubuntu-Studio-users@lists.ubuntu.com</a><br> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users</a><br> <br></blockquote></div><br>
