But, I am now seeing some errors that weren't there in 2.6.23
kernel: bttv0: SCERR @ 1fa0401c,bits: HSYNC OFLOW SCERR* last message repeated 15 times kernel: bttv0: timeout: drop=16 irq=105615/105615, risc=1fa0401c, bits: HSYNC OFLOW kernel: bttv0: reset, reinitialize kernel: bttv0: PLL can sleep, using XTAL (28636363).

These happen occasionally and it causes an EIO DQBUF error and the application has to re queue the buffers but it recovers OK. Not sure if it causes some sort of internal kernel corruption that will only be noticed later possibly?
I am using 15 userptr buffers so whatever is happening may be happening once per buffer sometimes. dunno
