Public bug reported: Lucid worked fine on this system, however since wiping over it with a vanilla install of Kubuntu Maverick 32 bit, every 5-20 minutes the kernel just hangs. I say it's the kernel as even Alt+Sysrq+RSEINUB does nothing. Anything animating on screen freezes and any audio playing stops, ruling out it being something like just being the mouse and keyboard.
If you look at the kern.log, the last hang happened at 8:45 on Nov 8 (today) and there seems to be a number of stack traces and similar in there, however I lack any skill to read them. The system was only just installed, and so is very close to vanilla. The only real changes have been updating all packages in the standard repo's and using nomodeset and radeon.modeset=0 as KMS seemed to make things run very sluggish. Xorg also restarts frequently (whenever I type a URL in rekonq, or come out of full screen video playback), although I think this is a separate problem as the kernel doesn't lock up in that case. Touch also doesn't work, however I read that this is a known problem from part of the driver being accidentally left out at the last minute by Ayuthia, and I haven't bothered to run his fix yet. Just mentioning in case it's related. I'll try the upstream kernel and see how that goes. Any other questions / suggestions welcome.
