Re: Linux Alpha port: LVM

[Rao Davide <davide.rao@atosorigin.com>]

Sorry to bother you all ... the problem was that I issued some options 
during configuration to specify where the kernel was, apparently I 
should only do that on 2.4 series kernels.

I re-extracted the kernel sources and started over again. It's nor 
working fine now.

Thanks anyway
