Jun 19 10:43:48 freebsd kernel: xl0: link state changed to DOWN

dmesg says: (minus the mac addys which Ive removed)

xl0: <3Com 3c905B-TX Fast Etherlink XL> port 0xec80-0xecff mem
0xfebfff80-0xfebfffff irq 11 at device 11.0 on pci0
miibus0: <MII bus> on xl0

ed0: <RealTek 8029> port 0xef40-0xef5f irq 10 at device 12.0 on pci0
ed0: type RTL8029 (16 bit)


ed0 is PCI card connected to a pppoe isp

xl0 is PCI connected to another computer via crossover/natted

The above happens if I use max upstream (60 KiloBytes/sec) on the pppoe
connection for a long amount of time (>6 hours).  Otherwise, everything
works fine.

Rebooting the machine is the only solution.  Killing pppd and restarting
does not obtain an ip from the isp.  And restarting xl0 also does not bring
back the lan connection.

6.0-Release is the version Im using.

Any ideas?  Besides not using any upstream. :)

All cards worked flawlessly in a linux system for 3 years.

System is a dual p2-333.  The kernel is SMP enabled.

Thank you.
