Hi Andreas, Harald,

the recent "SI generation" fix broke multi trx setups. This is because
when the first (c0) TRX is going up bts->si_valid will include SI2 and
other SIs scheduled on the BCCH and once the second trx is going up the
code decides it only needs to generate the SI5 (and more).

But si_valid still includes SI2 and it will be set on the second trx. I
have fixed it locally by setting si_valid to 0 early in the set_system_infos
routine and added a warning for this case.

How should this be properly fixed for master? Will the content of a specific
SI differ from TRX0 to TRX1 of a BTS? Should the si_valid be moved to the
trx data structure?

I have attached my local patch and would like to have a review for it.

comments? ideas?
