CentOS _dl_sysinfo_int80 deadlock

Are you using a CentOS or CentOS derived distribution and you experience deadlocks in dl_sysinfo_int80 function like this?:

#0 0x00ace7a2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2
#1 0x00cb248b in __read_nocancel () from /lib/tls/libpthread.so.0
#2 0x080bdf39 in el_push ()
#3 0x080bdfda in el_getc ()
#4 0x080bde50 in el_push ()
#5 0x080be11b in el_gets ()
#6 0x080a6f59 in main ()

Then you need to upgrade the kernel to the lastest version from the CentOS repositories (2.6.9-42.0.10.EL as of today):

yum upgrade kernel

Have Fun!
