I just had time to read the mailing list after several weeks and
stumbled accross this thread.
I have this error: "saa7146_i2c_writeout: timed out waiting for end of
This error occurs with and without the patch, but only on my modded FF
Card(TT1500 DVB-S) with 4MB. Any other card works flawlessly in the same

not modded and working just fine.
Could the problems be caused by the 4MB-Mod?
Have nice weekend.
