If I revert to the previous version, no packet loss at all. $FreeBSD: src/sys/dev/fxp/if_fxp.c,v 1.110.2.24 2002/08/09 02:04:20 luigi Exp $ vs $FreeBSD: src/sys/dev/fxp/if_fxp.c,v 1.110.2.23 2002/07/29 02:50:59 luigi Exp $ I confirmed this on 2 separate machines. The fxp nics in question are fxp0: port 0xa800-0xa81f mem 0xf9000000-0xf90fffff,0xfd000000-0xfd000fff irq 11 at device 13.0 on pci0 fxp0: Ethernet address 00:a0:c9:89:d5:ba inphy0: on miibus0 inphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto and fxp0: port 0xa000-0xa03f mem 0xe9500000-0xe95fffff,0xe9600000-0xe9600fff irq 10 at device 4.0 on pci2 fxp0: Ethernet address 00:d0:b7:db:69:6a inphy0: on miibus0 inphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto Both nics on both machines in question do have shard IRQs, but like I said, with the previous version of the driver it works fine. If I can provide any more information, please let me know. I do have a serial console on one machine and will have physical access to it once again on Monday. ---Mike At 08:53 PM 8/10/2002 -0400, Mike Tancsa wrote: >Actually, I am still seeing a lot of strange things.
