To get it right, my asus has the • tda10046a • saa7131e and not the saa7146 (which my brain generated using the numbers 7131 / 10046). On saa7131 board, the memory corruptions may be caused by V4L overlay interface. On overlay mode, the driver sets the device to do a PCI2PCI memory transfer.

AFAIK, some newer motherboards that had this problem can be corrected by upgrading its bios. That was what I told Soeren in the very beginning, but he does not even use any analog TV. The only case that I know of, that can cause menmory or file system corruption on that driver, is using DVB-T at once with planar video formats from other external inputs. Needs packed formats, because of some dma engines limitation here, according to Hartmut. Since we have other users of this later revision of that card, maybe not hardcored enough to run it over weeks, we should have at least one more to confirm that problem. I do not deny, that there can be an undiscovered issue. We had something similar with signal detection flaws previously on analog. Some apps did show it within 20 minutes, others only after two weeks ... Have not seen it myself until today, but was true.

This is with vanilla kernel 2.6.22.6, I wonder whether things could be better with hg - current? Anyway I suspect overruns of some buffers, which may even be caused by firmware bugs... but I have absolutely no idea where to look at. One way to debug things would be to alloc way too large buffers and then e.g. zero them and then check whether the expected part is still zero ... I really hope that you (or someone has an idea...).
