I have configured a Boca 16 port board, and have tried connecting a DSU to
most of the ports. I get massive character loss, and errors of the console
of silo overflows. I have options COM_MULTIPORT in my kernel config file
as well as the following:

device sio2 at isa? port 0x100 tty flags 0x1005
device sio3 at isa? port 0x108 tty flags 0x1005
device sio4 at isa? port 0x110 tty flags 0x1005
device sio5 at isa? port 0x118 tty flags 0x1005
device sio6 at isa? port 0x120 tty flags 0x1005
device sio7 at isa? port 0x128 tty flags 0x1005
device sio8 at isa? port 0x130 tty flags 0x1005
device sio9 at isa? port 0x138 tty flags 0x1005
device sio10 at isa? port 0x140 tty flags 0x1005
device sio11 at isa? port 0x148 tty flags 0x1005
device sio12 at isa? port 0x150 tty flags 0x1005
device sio13 at isa? port 0x158 tty flags 0x1005
device sio14 at isa? port 0x160 tty flags 0x1005
device sio15 at isa? port 0x168 tty flags 0x1005
device sio16 at isa? port 0x170 tty flags 0x1005
device sio17 at isa? port 0x178 tty flags 0x1005 irq 12 vector siointr

These are the types of errors I am getting :

sio2: 11 more silo overflows (total 11)
sio2: 11 more silo overflows (total 22)
sio2: 11 more silo overflows (total 33)
sio2: 12 more silo overflows (total 45)
sio2: 11 more silo overflows (total 56)
sio2: 11 more silo overflows (total 67)
sio2: 11 more silo overflows (total 78)
sio2: 11 more silo overflows (total 89)
sio2: 5 more silo overflows (total 94)
sio2: 7 more silo overflows (total 101)
sio2: 11 more silo overflows (total 112)
sio2: 12 more silo overflows (total 124)
sio2: 11 more silo overflows (total 135)
sio2: 11 more silo overflows (total 146)
sio2: 11 more silo overflows (total 157)

The port is only set at 19.2... any ideas? I am running version 2.2.5.

Thanks.
