Using EVMS craches my HP xw4300 and our HP nx8300. We have tried Gentoo sources 2.6.14-gentoo-r5 (and some of the below also with 2005.1r1): evms + BBR + lvm2 + XFS evms + MD + XFS evms + BBR + MD + XFS evms + BBR + MD + LVM2 + XFS evms + BBR + MD + LVM2 + XFS (on USB discs) Vanilla sources + BBR 2.6.14.2: evms + BBR + MD + LVM2 + XFS Sometimes a kernel panic. Most often just har lockup with no reactor to keybord. Once a reboot. I have two systems at home, one old IBM running EVSM + BBR + LVM2 + XFS and one ASUS P4P800 running EVMS + XFS working without problem. These machines are installed with 2005.0 and upgraded to latest gentoo kernel. EVMS + XFS as compability volume works. We also always gets the minimal md reconstruction speed. I don't know if this is related.

Pure md without evms gives high reconstructions speeds
Setting kernel stack size 8k did remove the problem.
Do you think you could test the latest development kernel (currently 2.6.16-rc1) and see if 4k stacks work ok there? I know there has been work to reduce stack consumption on storage chains like this, but it would be useful to report the issue if it is not completely fixed.
