fxp timeouts

[Rui Paulo]

Hi,
On a RELENG_7 machine, after a few days of uptime, I started getting fxp 
DMA and SBC timeouts:

May  8 19:59:33 sigma kernel: fxp0: DMA timeout
May  8 19:59:33 sigma kernel: fxp0: SCB timeout: 0xff 0xff 0xff 0xffff

And this goes on forever until I reboot:

% zcat /var/log/messages.1.bz2 | egrep -c '(SBC|DMA|timeout)'
1785

Has anyone else experienced this problem ? Am I having hardware problems 
? I never had any problems with this card, but I recently put some extra 
load on this server.

Regards,
