Kernel oops in bt878 module

[Lauri Nurmi]

Binary package hint: linux-image-2.6.15-26-686

Steps to reproduce:

1. Install four bttv-based video capturing PCI cards on a PC, each card having four bttv chips.

2. Boot up the system with 2.6.15-26-686 kernel.

3. A kernel oops will occur (every time), and the system will lock up.

Points worth noting:
* Using 386-optimized kernel, 2.6.15-26-386, this problem does *not* occur.
* With only three cards installed (and thus twelve video4linux devices), this problem does *not* occur with the 686 kernel either.

Hardware information:
Asus P4P800-SE motherboard

processor : 0
vendor_id : GenuineIntel
cpu family : 15
model : 2
model name : Intel(R) Pentium(R) 4 CPU 2.80GHz
stepping : 9
cpu MHz : 2799.251
cache size : 512 KB

The bttv cards have video inputs only, no tuners, no audio input.
