I usually see stalls sending data from machine A to machine B. I just upgraded machine B to commit 8d9107e8c50e1c4ff43c91c8841805833f3ecfb9 (Fri Jul 13 16:53:18 2007 -0700) and the tree includes this patch. This did not, however, fix the problem so I guess the problem is on the sender side. Due to wireless-dev lagging behind I there still have 2.6.22-something where this patch doesn't apply. I hope John will merge again soon and then I'll report back whether I still see the stalling behaviour with a current tree that includes this patch. johannes --=-mm+nRoCVK/UYFT/q5Vx+ Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iD8DBQBGmzA5/ETPhpq3jKURAo53AJsHUboxUdV6PgEdFOGJOlSZIP+q0ACfep30 4S7dA9i8w0r6Pd9hJwbtLac= =kTZ2 -----END PGP SIGNATURE----- --=-mm+nRoCVK/UYFT/q5Vx+--
