It seems I'm being guilty to this one, Dave please apply to net-2.6.22 
(besides this I think the tcp_sync_left_out should be changed but I'll 
prepare a patch for that later). Btw, how should this kind of email with 
some non-patch description+patch be formatted?).

Thanks for figuring out the problem so quickly, this formatting
is fine.

[PATCH] [TCP]: Timedout loop must skip SACKed skbs too while marking

Marking skb with both S and L is invalid, and that could easily
happen in the timedout loop. Later on the tcp_sync_left_out
reduces sacked_out if lost_out + sacked_out > packets_out and
then eventually sacked_out underflows triggering a debug trap in
tcp_clean_rtx_queue.

Patch applied, thanks a lot!
