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? Good luck!
