I patched it into the kernel plus activated CONFIG_FRAME_POINTER which led to the same hang (not surprisingly, the patch does only debug more ;-) This time unfortunately I there was too much output to actually capture it. @Johannes: 100% reproducible. Everytime I boot into 33-rc4 and ssh into any remote place it goes boom. 100%. Maybe another tidbig might help: With 2.6.32.3 it happens that I have hickups with WLAN: [ 996.514491] iwlagn 0000:06:00.0: iwl_tx_agg_start on ra = 00:24:c4:ab:bb:42 tid = 0 and the connections needs 10-20secs (hard to guess) until it is back alive.
