Hi!

I have a trouble with my 16-port Cyclom-Y PCI card under
FreeBSD 2.2.2. I have "silo overflow" error during
intensive transfering incoming data. Port speed is 115200.
Modem speed - 33600. Only one line of total 9 is active.

My hardware:
P-133, 32M RAM, 2G SCSI HDD on NRC-810 based SCSI adapter.
Cyclom-Y on IRQ 10,
NRC-810 on IRQ 11,
PCI video card on IRQ 12.

How I can solve problem with data loss.

Best wishes,
Sergey

P.S. Fragment of my kernel configuration file:
