Thanks for the report, I've been away for a while, thus the late response.
Please update to get this relevant fix and some other TCP fixes (if you 
haven't yet):

 releases/2.6.25.7/tcp-fix-skb-vs-fack_count-out-of-sync-condition.patch

...If you still get them afterwards, please do rereport (and include me 
as recipient :-)). ...I know there are couple of cases still after that 
fix where TCP invariant checks trigger but they've been rare enough to 
evade any of my debugging attempts (2.6.22.17 won't warn you anyway when 
it breaks an invariant though I already know a handful violations that 
do occur with it too but there's just plain silence because I only later 
on added those warning).
