Hi Pasi,

Pasi: do you see a possibility  to try it out on 2.6.18 ? I'm not sure
if anybody from Fujitsu takes
actively care, it is quite old code.

Jan: but if I understood Pasi, he claims there are no pvscsi drivers
included in the pv-ops tree at all
because it was not ported so far.
But your opensuse pv-ops kernel definitely includes pvscsi drivers -
does this part exist only in
suse kernel tree ?
