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.
