spin_lock problem in recent kernel

Hi!

I had tried SMP kernel using paulus rsync tree and 2_4 bk tree.
Since 2.4.3pre6 it has spin_lock problem in both tree.

I used that patch when pre6,pre7
Then I could boot kernel and it's work well.

2.4.3pre8 is not boot that has the other spin_lock problem.
(around ip_tables loading)

When i used this patch when pre6, pre7.

Please check spin_lock problem of pre8 with SMP kernel.

the machine is G4 dual
Thanks

Kaoru
