Hi, Has anyone tried running a gcc4 build on real hardware recently? It seems incredibly unstable compared to the gcc2 equivalent (i.e. I had to exclude the radeon driver from the build to get the display to not go insane when the app_server starts, even with failsafe mode chosen from the boot menu). Specifically, even idling it doesn't manage to stay up for more than roughly 1-2 minutes before hitting KDL with a double fault, though the backtrace from the kernel doesn't make it obvious exactly what triggers it. The same machine can run the gcc2 version perfectly for days on end. Any thoughts on how to go about debugging what's going wrong here? Would fixing gcc4 warnings found throughout the code possibly help? Regards, Rene
