The reply from Bodo Eggert seems to indicate otherwise.. Here is some extra information as requested: > 1) desactivate any overclocking at motherboard/video board; I do not use any kind of overclocking, never have done and never will! > 2) use a standard vanilla kernel (not a distro kernel, that may have > some experimental patches applied; The crashes I reported were on a vanilla 2.6.12 kernel, compiled straight from the tarball on kernel.org. > 3) use a minimum ammount of cards leaving only neccessary cards at MB. > For these, it is good to clean its contacts; The only extension cards I use are: - 1 nVidia GeForce 6800 video adapter - 1 Pinacle PCTV card - 1 3Com 3c905C ethernet card - 1 SB Live! 1024 card I regularly vacuum-clean my tower and have checked the contacts on the extension cards on several occasions. For tests, I am willing to remove the NIC + soundcard if you think that will help (will try over the weekend), but in the long run I don't consider any of the above cards to be "exotic" or optional.. > 4) Test it again. Will do, as stated above. On a sidenote, so far I have been unable to reproduce the problem when PREEMPT is disactivated (I stressed my box by compiling a kernel while watching TV).
