The problem is in established_get_next() and established_get_first() not allowing softirq processing, while scanning a possibly huge hash table, even if few sockets are hashed in.

As cond_resched_softirq() was added in linux-2.6.11, you probably *need* to check the diffs between linux-2.6.10 & linux-2.6.11

Thanks for the pointers to the likely culprits.
