Just to make some clarifications: The random Sig 11's are observed in the stock XFree86 4.x drivers with none of the 'extras' enabled, such as DRI on several sets of video cards (Matrox and ATI). I can run both UP and SMP kernels in the 2.2 series and 2.4 UP kernels with unlimited uptimes. However, switching to a 2.4 SMP kernel will cause random Sig 11's in X, seemingly irregardless of video card/vendor.=20 The systems are all stock hardware as well as the distros (excluding errata). It's difficult to ascertain information on this problem due to the 'randomness' of the crashes. I don't have to do anything unusual to cause this crash: Just install a recent distro on an SMP machine, stare at the screen, and X will eventually crash. I'm not totally convinced that this is a kernel problem, but it seems that only a handful of people seem to be aware of this. (This has been going on for well over a year, around the time of the mid-2.3 kernels).=20 The fact that a 2.4 kernel seems to be catalyst lends some creedence to this theory. Jeffrey H.
