CRC and Frame Errors

I have a Dell PowerEdge 350 rackmount server I've refurbished, running pfSense Release 1.0.0. It is running a single 850MHz Celeron processor and 512MB RAM. As with all PowerEdge 350 models, it comes equipped with on-board Intel Intel Pro/100+ adapters. Additionally, I've added an Intel Pro/100 S Dual Port Server Adapter for a total of 4 independent ethernet ports.
The device is connected to an ethernet uplink operating at 10/Full and an ethernet downlink operating at 100/Full to a Cisco 2924-XL switch, using VLANs.
The problem is that under load (>4Mbps throughput) the switch starts to show frame and CRC errors from the device. I've tried all 4 ethernet ports, multiple ports on the switch and changing ethernet cables (BTW, it's only about 5 feet long) to no avail. Autosense is disabled and all ports are locked to the proper speed and duplex settings.
Any ideas what could possibly be wrong?????

Turn back on autonegotiation. Setting modes to only one end where the other end is doing autonegotiation can have some strange effects.
