eth0 TCPv4 checksum failed in 2.2.0preX

I keep getting TCPv4 Checksum Failed messages in my kernel logs since
upgrading to 2.2.0preX (pre1, 3, and 4 all have the error). This is NOT
a PPP connection (as in other TCPv4 checksum failed threads on this
list) but a 100Mbps full-duplex Ethernet connection.

- SuperMicro P6DNF
- Dual PPro 200Mhz
- 128MB 60ns EDO RAM
- DPT PM3334UW PCI (EATA/DMA)
- Adaptech 1542CF ISA
- 3c905 NIC

I'm running Red Hat Linux 5.2 with all of the latest updates. My SMP
kernel is not modular and MTRR is enabled. I've even used the latest
3c59x.c (0.99H) which is supposed to handle SMP better but the error did
not go away. I do not see this error in 2.0.35/36 (non SMP).

Can anyone shed any light on this situation? Thanks!
