[Lustre-discuss] Problems & partial success on PPC64 (XServe G5) Debian cluster

[Robert Olson]

Hm, ok. (Unfortunately the bigendian server is where I'm going with  
this, but it will be useful to get things going with the intel  
hardware first,  make sure I know what I'm doing).

I'd love to go to the newer kernel, thought we were stuck at 2.6.18  
with the vanilla series patches - is that not the case?

thanks,
