Oracle 5 UEK VM interrupts gotcha

The good news is that the latest VMWare Player VMWare Tools (4.0.2 build-591240) now work with the Oracle Linux 5 UEK linux kernel but the bad news is that the ‘divider=’ kernel option seems to be ignored  by the Oracle UEK kernel so you may need to switch back to the regular kernel if you wish to reduce the number of interrupts generated by all your Oracle Linux 5 vms !

heres an extract from my /boot/grub.conf
