	Hello Bob,

	I'm testing some configurations with 2.6.18.2 linux kernel. This kernel=20
boots wihtout any trouble and I believe that all troubles we have seen=20
are fixed.

	With SuperSparc-II, kernel seems to be stable, but I'm not able to=20
untar a linux kernel without receive "t=E2che interrompue" (unterrupted=20
task) or an Oops :

Unable to handle kernel NULL pointer dereference

	I think that the trouble I have seen with HyperSPARC comes from the=20
