Kernel is 2.6.15-gentoo-r1, using usbvision 0.9.8.3.
It compiles and modprobes ok, and dmesg shows:
| Code: | Linux video capture interface: v1.00

But then when I start a video app like tvtime or xawtv, I get this in dmesg:
| Code: | Unable to handle kernel NULL pointer dereference at virtual address 00000000
printing eip:
00000000
*pde = 00000000

Then the app freezes.
Any ideas? |
