I'm getting the following bad message:

/netbsd: sd0(esp0:0:0): esp0: timed out [ecb 0xf04698fc (flags
0x43, dleft 2000, stat 0)], <state 4, nexus 0xf04698fc, phase
(l 3, c 3, p 3), resid c00, msg(q 20, o 0)>

what does this mean?  How to correct it?


Also,


How to boot a disk on the SECOND scsi controller ?

right now I use
boot-device = /iommu/sbus/espdma@4,8400000/esp/sd@0,0

to boot sd0,0 on the onboard controller.  How would I
boot from a disk on a plug in controller?  It's a LX machine.
