mysql stops working after kernel upgrade

[Ankush Grover]

hey friends,

I recently installed FC3 on a machine and today I installed the new
kernel "2.6.11-1.35_FC3".Since then mysql has stopped working.The
problem is with SELinux.
If I disable the SELinux for mysqld ,the mysql starts working properly
and keeps on working properly ,but if I enable SELinux for mysqld and
then reboot the machine the problem starts.

 I have tried "restorecon -R /var/lib/mysql" "make -C
/etc/selinux/targeted/src/policy reload"
and also /.autorelabel. But nothing is working for me. I am using
MySql 4,I downloaded the rpms from the Mysql.com site.
