Hartmut,
Here is the debug output (some lines, I can give you more if you want
:-) )
Dec 17 17:09:43 VDR kernel: saa7146_i2c_writeout(13c2,0000): timed out

It comes from your FuSi FF card.
I assumed this due to the PCI id.
Dec 17 17:09:43 VDR kernel: EIO after saa7146_i2c_writeout:
count=1(2), data=0x86000040, addr=0x09, R/W=W, buf[0]=0x00
I think that this comes from ves1820_readreg(). The failing transfer is
always the second message. I would like to see the affected register,
but for the ves1820 the first value is the sub-address. I've modified
the patch a little bit. Now it prints also the register.
If your kernel is configured with a timer frequency of 100Hz or if your
pc runs with a high load, the timeout value of 10ms may be to small. The
second patch increases the timeout value to 50ms.
This is a standard Suse 10.2 kernel which is built with CONFIG_HZ=250
The load is rather low, only VDR is running <10% CPU.
Unfortunately the increased timeout didn't change anything.
But with CONFIG_HZ=250, the timeout was still at 10ms. I now changed it
to 20*HZ/100, now the frequency of the message has decreased, but it
still occurs. I'll retry with increased values. 50*HZ seems to work.
I'll try to find a minimum. No 50 isn't enough. Still messages occur ...
Regards
Dominik
