I have very similar issue with a Twinhan DVB-S board, here are the
latest messages from my system:

Apr 11 22:09:36 tv bt878(0): irq FDSR risc_pc=1f28a0c0
Apr 11 22:11:00 tv bt878(0): irq FDSR risc_pc=1f28a158
Apr 11 22:15:13 tv bt878(0): irq FDSR risc_pc=1f28a1e0
Apr 11 22:21:10 tv bt878(0): irq FDSR risc_pc=1f28a118
Apr 11 22:21:30 tv bt878(0): irq FDSR risc_pc=1f28a210
Apr 11 22:28:31 tv bt878(0): irq FDSR risc_pc=1f28a120
Apr 11 22:31:39 tv bt878(0): irq FDSR risc_pc=1f28a140
Apr 11 22:40:26 tv bt878(0): irq FDSR risc_pc=1f28a1a0
Apr 11 22:45:20 tv bt878(0): irq FDSR risc_pc=1f28a0b8

On my case look like the beginning of the 32bit location is constant and
the second LS 16bit are changing.
By looking back to my system log I see the message start with my upgrade
from 2.6.5 kernel to Now I use
My kernel was compiled without SMP.
My CPU is a P4 Celeron at 2.4GHz and mainboard have SiS 955 chipset.
I use this system as a Sat PVR and the system does not have keyboard or
monitor and I cannot confirm is frequency of this message change when I
use the system interactively.

I hope that we find a solution to this issue before my HDD will be full
because of the logging :-)
