Problems with 2.4.3 — Video for Linux

I am using a ixMicro TurboTV on 2.4.3 with bttv 0.7.57 and when I load
the bttv modules, I get the following:

bttv: driver version 0.7.57 loaded
bttv: using 2 buffers with 2080k (4160k total) for capture
bttv: Bt8xx card found (0).
PCI: Found IRQ 10 for device 00:0a.0
IRQ routing conflict in pirq table for device 00:0a.0

I did not have this problem with earlier 2.4.x kernels nor 2.2.19.
Here's the relevent output from lspci:

00:00.0 Host bridge: VIA Technologies, Inc. VT82C595/97 [Apollo VP2/97]

        Flags: bus master, 66Mhz, medium devsel, latency 64
...

        Subsystem: 3Com Corporation 3C905B Fast Etherlink XL 10/100
                Flags: bus master, medium devsel, latency 64, IRQ 10
...
00:0a.0 Multimedia video controller: Brooktree Corporation Bt848 TV with
DMA pus
h (rev 12)
        Flags: bus master, medium devsel, latency 64, IRQ 5

When I start xawtv, the machine freezes and requires a hard reboot.  Is
this information helpful to anybody?  As I mentioned previously,
everything worked fine under earlier kernels.

Thanks,

Mike.
