I've had this problem for a while now, reported it back in 2.3.x somewhere. I havn't needed v4l so I ignored it. Playing with my bttv again and having a lot of trouble
After some (random) amount of frame grabs, my system loses. Badly. ethernet quits forwarding, IDE refuses to respond... All I can do is switch VCs and watch errors scroll by.
This may be a chipset problem, although I've seen reference to others having problems with this driver and IDE in the past.
Tested with v4l1/2 for all kernels up to 2.4.0-test12
Lockup still happens if IDE DMA is disabled.
Please Cc: me if you want any additional information, I read L-K via the web archives.
