Problems with r8168 on AMD64

Hello.
I have a new HP Pavilion Intel Core2 Quad machine with the following
onboard Ethernet controller:
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02)
Subsystem: Hewlett-Packard Company Device 2a6f
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
Latency: 0, Cache Line Size: 32 bytes
Interrupt: pin A routed to IRQ 2298
Region 0: I/O ports at e800 [size=256]
Region 2: Memory at febff000 (64-bit, non-prefetchable) [size=4K]
Region 4: Memory at f8ff0000 (64-bit, prefetchable) [size=64K]
Expansion ROM at febc0000 [disabled] [size=128K]
Capabilities: <access denied>
Kernel driver in use: r8168
Kernel modules: r8168
As you can see, I'm using the r8168 driver (the latest one available
from the realtek site). I compiled it and installed it according to
the instructions I found at
http://ubuntuforums.org/showthread.php?p=6441406.
The driver works for a while, but seems to crap out after a little
while -- typically during a large download. ifconfig shows that the
card is still up, but no packets are received. dmesg provides no
information about the failure that I can see. You can see here the
output of dmesg when I've loaded the module. There's nothing in dmesg
about the card going down.

If I rmmod and modprobe r8168, then the card works normally (for a
while).
I've also tried the r8169 driver (the one selected on a clean install
of AMD64 Ubuntu 8.10), but the behavior is just the same. It works
for a while and then silently fails.
Here's the output of ifconfig while the card is working.
eth0 Link encap:Ethernet HWaddr 00:1e:8c:4d:00:a8

I'm bumfuzzled. It's been a long time since I had any trouble getting
an ethernet card to work on Linux, so I'm a bit disappointed with this
problem. Any help would be greatly appreciated.
Thanks much.
(Pardon me if this is a duplicate. My previous NNTP server has been
flaky.)
