------- Additional Comments From soulglo83@aol.com 2006-02-02 23:48 ------- i can confirm this bug as well, previously running ubuntu breezy 5.10 w/ kernel revision 2.6.10 under xorg 6.9 RC4 using ALSA. both wine-preloader and wineserver appear to be gobbling up cpu time until the system becomes unstable, ctrl + alt + f1-f6 will temporarily release a hold on some of the cycles and appear to "unfreeze" the application. recently i read somewhere someone with kernel 2.6.15 was running steam flawlessly, and so i decided to upgrade, i patched a vanilla 2.6.15 from kernel.org following the how-to's assembled in this post (for ubuntu users, w/ some modification may apply to debian) :
