2.6.9-rc1+bk: assertion tcp_get_pcount failed at net/ipv4/tcp_input.c

[Alex Riesen <fork0@xxxxxxxxxxxxxxxxxxxxx>]

The box froze after being left for some time (some 10 hours) unattended.
The only thing in I could find in logs was:

Sep  8 22:30:18 steel kernel: KERNEL: assertion 
((int)tcp_get_pcount(&tp->lost_out) >= 0) failed at net/ipv4/tcp_input.c (2422)
Sep  8 22:30:18 steel kernel: Leak l=4294967295 4
Sep  8 22:32:49 steel kernel: KERNEL: assertion 
((int)tcp_get_pcount(&tp->lost_out) >= 0) failed at net/ipv4/tcp_input.c (2422)
Sep  8 22:32:50 steel last message repeated 2 times
Sep  8 22:32:50 steel kernel: Leak l=4294967295 3

This can probably be not the reason. I do not know the actual time.
There should have been some traffic (two bittorrents were running).

The .config attached.
