>Description:
The machine has 3 serial 8-port-cards installed, 2 of them ISA cards
and one PCI card. The card model of all 3 of them is Moxa SmartIO
C168H (http://www.moxa.com/Product/C168H.htm and
http://www.moxa.com/Product/C168HPCI.htm). Since Upgrading to
5-Stable the ISA cards have high numbers of silo overflows. This did
not happen with 4-Stable.
The overflows happened with SCHED_4BSD or SCHED_ULE, with and
without PREEMPTION in the kernel, and regardless of baudrate (I
tried 9600 and 115200). Also I tried several HZ values in the kernel
(100, 1000 and 4000), and it didn't matter.
The machine is a PII with 300 MHz. Now this isn't the most powerful
(and ISA is a little bit old-fashioned), but the effect happens also
when only one of the 24 ports is used and it's at 9600 Baud, and
anyway with 4-Stable there was no problem at all.
Here is the machine's dmesg:

>How-To-Repeat:
Connect to another FreeBSD machine via such a serial line and

afterwards.
