The reset and abort handling in the mesh driver needs to be updated;
the way the scsi mid-layer expects them to work changed during the 2.1
series but I haven't updated the mesh driver to the new way yet,
partly because I don't know exactly what the new way is. :-)

It's working OK for me now with a 2.3.4 kernel, having fixed ioremap
(the fix is now in vger for both the 2.2 and 2.3 branches).

If you want to disable sync mode, you could change the initializer for
mesh_sync_targets in drivers/scsi/mesh.c from 0xff to 0.
