I look in archive, but I didn't find any tip. I have ATI TV Wonder PCI (stereo), kernel 2.4.2, videodev and i2c compiled in kernel (not as module, it may be wrong). Insmod tuner type=19 (Temic 4006 FN5) is OK, in syslog I see "i2c is registering ......" I try "lspci -v" and got (part) 00:08.0 Multimedia video controller: Brooktree Corporation Bt878 (rev 02) Subsystem: ATI Technologies Inc: Unknown device 0001 Flags: bus master, medium devsel, latency 64, IRQ 11 Memory at e2000000 (32-bit, prefetchable) [size=4K] 00:08.1 Multimedia controller: Brooktree Corporation Bt878 (rev 02) Subsystem: ATI Technologies Inc: Unknown device 0001 Flags: bus master, medium devsel, latency 64, IRQ 11 Memory at e2001000 (32-bit, prefetchable) [size=4K] When I try insmod bttv whole system freeze (with param bttv_verbose=2 I got message sounds like " device 00:08.0 using IRQ 11 and device 00:08.1 using the same IRQ". Then I can only power off/on :-( (sorry for my English) PAT
