It seems to me that there are maybe more issues in the radeon drm driver, see http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/72224 (the synopsis is actually not precise as the problem seems to be more drm specific than umass related). Btw, sleep works fine on my R40, while suspend is somehow completly broken. Vaclav Rehak
