RE: Kernel downgrade

Nitai,

why did you need to use --force ?

You can see from the grub.conf you supplied below that 
2.6.9-22.0.2.ELsmp is 0
2.6.9-22.0.2.EL is 1
etc

so yes, just change default to wherever your new kernel is in the list.

Im worried about why you needed to force the kernel to install tho ... be prepared for possible issues when you reboot then new kernel ;)

Good luck,
Nick .
