Reading dmesg uncovered "can't claim BAR" errors. Looking for this in my other test machines I see more of them - on many sparc64 machines and some on x86. In another thread for "Resource allocation cleanup for v4.4", Yinghai Lu asked for full dmesg to solve another similar case. So to help understanding this one, here are the dmesgs of my machines: sparc64 machines: http://kodu.ut.ee/~mroos/dm/dm.t1-105 http://kodu.ut.ee/~mroos/dm/dm.t1-200 http://kodu.ut.ee/~mroos/dm/dm.v120 http://kodu.ut.ee/~mroos/dm/dm.v210 http://kodu.ut.ee/~mroos/dm/dm.v240 http://kodu.ut.ee/~mroos/dm/dm.sb100 amd64 machine: http://kodu.ut.ee/~mroos/dm/dm.x2100 -- Meelis Roos (mroos@linux.ee)
