For sure breakage is between -rc2 and -rc3 ?
We have these commits:
$ git log --pretty=oneline v2.6.35-rc2..v2.6.35-rc3 -- net/mac80211/ drivers/net/wireless/iwlwifi/
b054b747a694927879c94dd11af54d04346aed7d mac80211: fix deauth before assoc
6db6340c42d027b6364d49fa99d69019aca24de4 iwlwifi: add missing rcu_read_lock
35dd0509b21e4b5bab36b9eb80c8dab0322f5007 mac80211: fix function pointer check
7d47618a2ade0cb6d8a0b2597029c383c1662fa0 iwlwifi: move sysfs_create_group to post request firmware
1402364162afbaac1b8a74ee21aeb013e817ac7d iwl3945: fix internal scan
a6866ac93e6cb68091326e80b4fa4619a5957644 iwl3945: enable stuck queue detection on 3945
8b9a4e6e442756f670ef507f09bbc6c11dc0fca6 mac80211: process station blockack action frames from work
Also there are some general network commits.
What I can tell, none of them could cause performance problems in
obvious way. If breakage is really between 2.6.35 -rc2 and -rc3, could
you install 2.6.35 kernel from source, and revert these commits
one by one to see revert of which commit fix the problem?
