Ok.. I read all posts (I only find 3 o 4 ??) and in special mails of
Simon Graham about this theme.
as far as I understand, there are two options:

1 - disable rx/tx checksum and sg for this interface.
what consequences or problems I should waiting ??

2 - change DRBD protocol from C to A.
but.. in this case (IMHO, more easy) I would can data lost.
in second scenario... I think that I should have one scheduled job of
verification in short period of time or no ?

others two questions:
1 - how I can test if this changes work fine ???
exist one method of make a system crash test ??

2 - what of options above is more recommendable ??
