I think the problem is the

le0             at lebuffer?                            # SBus

line in the GENERIC config file.

I don't know exactly anymore what goes wrong with it - somehow the kernel
mixes the dma for scsi with ledma or something like that, because it
trys to find a match for that second le it finds. (Well, that's my highly
speculative idea :-)

Changing that to le* fixes it for me.

I have

# FSBE/S SCSI
dma*    at sbus? slot ? offset ?                        # SBus
#esp*   at sbus? slot ? offset ? flags 0x0000           # SBus (older proms)
esp*    at dma? flags 0x0000                            # SBus

[...]

#le0            at obio0 addr 0xf9000000 level 6        # sun4/300
#le0            at sbus0 slot ? offset ?                # sun4c on-board
ledma0          at sbus0 slot ? offset ?                # sun4m on-board
le0             at ledma0                               # sun4m on-board
#le*            at sbus? slot ? offset ?                # SBus
#ledma*         at sbus? slot ? offset ?                # SBus
#le*            at ledma?                               # SBus
lebuffer0       at sbus? slot ? offset ?                # SBus
le*             at lebuffer?                            # SBus
#lebuffer*      at sbus? slot ? offset ?                # SBus
#le*            at lebuffer?                            # SBus

in my config file and both the ethernet and scsi part of my
FSBE/S scsi card work fine in my SPARCclassic X (Sun4m).
