 SS5 with 1.6_BETA3 I saw message below, and system hang. This does not
happen at boot time.

| sd0(esp0:0:3:0): esp0: timed out [ecb 0xf055b0e0 (flags 0x101, dleft 0, stat 0)], <state 1, nexus 0x0, phase(l 10, c 100, p 3), resid 0, msg(q 0,o 0) >

With 1.5.3_RC2, this drive works without problem, and I notice that
there is no "tagged queueing" on dmesg.
