I have this problem for some time with any kernel after 2.6.11-rc3. I'm 
using 2.6.10 right now and it is working fine.

Here are the last line from syslog using 2.6.11.4:

    |Linux video capture interface: v1.00
    bttv: driver version 0.9.15 loaded
    bttv: using 8 buffers with 2080k (520 pages) each for capture
    bttv: Bt8xx card found (0).
    ACPI: PCI interrupt 0000:00:0a.0[A] -> GSI 10 (level, low) -> IRQ 10
    bttv0: Bt878 (rev 17) at 0000:00:0a.0, irq: 10, latency: 32, mmio:
    0xe7800000
    bttv0: detected: Twinhan VisionPlus DVB-T [card=113], PCI subsystem
    ID is 1822:0001
    bttv0: using: Twinhan DST + clones [card=113,autodetected]
    bttv0: gpio: en=00000000, out=00000000 in=00f5ffff [init]
    |

And for comparation, here is the output from 2.6.10 on the same system 
(2.6.10 is work fine):

    |Linux video capture interface: v1.00

The system just freeze when loading bttv driver. I was able to capture 
this line from syslog because I have a dedicated system for logging.

I have tested and the problems is still in 2.6.12-rc1-bk3.
I have also tried to move my DVB board to different systems and I see 
same hang when loading bttv. I have tried P3 and P4 systems with SiS, 
VIA and Intel chipsets.

Thanks,
