[CentOS] Some thoughts about EL 6

Many people seem to wait for the announcement of CentOS 6.0, so I want
to share some test results I did with SL 6.0..

The actual 6.0 kernel can NOT allocate tape buffers when the server is
heavily loaded at least on some LSILogic hardware.
There is a big problem of slab buffer increase that can cause
reboot/freeze of the server under load. Reported by many and verified by
me :-(

So perhaps it's a good idea to wait for 6.1 for mission critical servers..
