Here are four logs from doing:

	scandvb -a1 ./e.1

where the contents of file e.1 are:

	S 11919000 V 27500000 3/4

which is probing a region on the Eutelsat-9A satellite broadcast.

I inserted:

	diff -uNr linux-3.11.7-300.dvbsky_4.fc20.x86_64/drivers/i2c/i2c-core.c i2c-monitor/drivers/i2c/i2c-core.c

		orig_jiffies = jiffies;

into the kernel to generate these logs.

The four logs are:

 (1) DVBSky's megapatch: I2C traffic generated by cx23885 module initialisation
     and probing.

 (2) DVBSky's megapatch: I2C traffic generated by the aforementioned scandvb
     command.

 (3) Antti's drivers plus my S952 glue: I2C traffic generated by cx23885
     module initialisation and probing.

 (4) Antti's drivers plus my S952 glue: I2C traffic generated by the
     aforementioned scandvb command.

The scandvb command with the DVBSky megapatch gave:

	dumping lists (25 services)
	Italy Service:11919:v:0:27500:2003:3003:3
	Karusel int:11919:v:0:27500:2004:3004:4
	SVT WORLD:11919:v:0:27500:2008:3008:8
	...

and was very consistent.

Antti's patch gave:

	dumping lists (22 services)
	[0001]:11919:v:0:27500:0:0:1
	[0003]:11919:v:0:27500:0:0:3
	[000d]:11919:v:0:27500:0:0:13
	...

and sometimes:

	dumping lists (0 services)

and once:

	dumping lists (32 services)
	[f714]:11919:v:0:27500:0:0:63252
	[e38b]:11919:v:0:27500:0:0:58251
	[b7ba]:11919:v:0:27500:0:0:47034
	...
