Hi.I have been running MySQL 4.1.0 on my SMP machine for monthes, it is not P4 HyperThreading,
This patch did not fix the problem. On the 4th boot system hang with same symptoms.

I have one strange problem with mysql 4.1.0 when using KSE on 5.1-CURRENT.
but a dual P3 machine, it just works fine for me.
Did kernel lock up or can you press ctrl+c to see if you can interrupt it ?After building mysql server with libkse as thread library and adding its start script into /usr/local/etc/rc.d, system hangs on boot without any error message when mysql trying to start.
If you build mysql from ports, it should install script mysql-server.sh under /usr/local/etc/rc.d,If I trying to start mysql by hands after system completely boot then everything works just fine.
If I add delay into mysql start script and run it in backgroud from rc.d - everything is fine
the default script will run mysqld_safe in background, I am confused that you need to
manually turn it into background, the work should be done atomically by the script.
If I build mysql without KSE it works fine.
I'm not sure, but try this patch; it duplicates what libc_r does.
