mysql wont start with new kernel

[dragoran]

I installed kernel 2.6.11-rc3-RT-V0.7.38-01 (compiled it from source) I 
did make oldconfig and  enabled PREEMT_DESKTOP ,CONFIG_MK7 and ntfs support.
After booting the kernel mysql don't start:
It shows:
Timeout error occurred trying to start MySQL Daemon.
dmesg says:
audit(1107676996.424:0): avc:  denied  { execmem } for  pid=4806 
comm=mysqld scontext=root:system_r:mysqld_t 
tcontext=root:system_r:mysqld_t tclass=process
it works when I disabled selinux for mysqld.
I am running the targeted policy.
