LVS in 2.4.23: crash in ip_vs_conn_unhash

["Brett E." <brettspamacct@xxxxxxxxxxxxx>]

I see that ip_vs_conn_unhash has been changed from ipvs in 2.4.23 to the 
ipvs in 2.6.2 so is this a known bug that was fixed?
I'm using LVS from 2.4.23 on a 2 way SMP machine and kdb crashes in 
ip_vs_check_template, I'm leaving kdb up and running, but here's the 
data I transribed by hand, hopefully I didn't make any typos:
