The second options line option of combfilter by docs indicate there is no 2 option and is enabled by default, so you can remove that option to test. I would enable two possible compatibility options and see if that helps. triton1=0/1 - for Triton1 (+others) compatibility. vsfx=0/1 - yet another chipset bug compatibility bit The triton1 insmod option sets the EN_TBFX bit in the control register. The vsfx insmod option does the same for EN_VSFX bit. If you have stability problems you can try if one of these options makes your box work solid.
