So far I have not been able to duplicate it using the kernel.  It happens using the kernel.

Once the connectivity is lost, I see repeating blocks of

transmit timed out

eth0: Transmit timeout, status 0c 0005 c07f media 00.

eth0: Tx queue start entry 4  dirty entry

eth0:  Tx descriptor 0 is 0008a042.
(queue head)

eth0:  Tx descriptor 1 is 0008a04a.

eth0:  Tx descriptor 2 is 0008a042.

eth0:  Tx descriptor 3 is 0008a04a.

eth0: link up, 100Mbps, full-duplex, lpa 0x45E1

Prior to that, everything looks ok.  Here are the relevant parts of dmesg:

8139cp: 10/100 PCI Ethernet
driver v1.3 (Mar 22, 2004)

8139cp 0000:0a:0c.0: This (id 10ec:8139 rev 10) is not an 8139C+ compatible

8139cp 0000:0a:0c.0: Try the "8139too" driver instead.

parport_pc 00:0a: reported by Plug and Play ACPI

parport0: PC-style at 0x378 (0x778), irq 7 [PCSPP,TRISTATE]

8139too Fast Ethernet driver 0.9.28

ACPI: PCI Interrupt 0000:0a:0c.0[A] -> GSI 17 (level, low) -> IRQ 25

eth0: RealTek RTL8139 at 0xf8934000, 00:c0:f0:68:47:5a, IRQ 25

eth0:  Identified 8139 chip type

SELinux: initialized (dev ramfs, type ramfs), uses genfs_contexts

NET: Registered protocol family 10

Mobile IPv6

Netfilter messages via NETLINK v0.30.

nf_conntrack version 0.5.0 (8192 buckets, 65536 max)

ip_tables: (C) 2000-2006 Netfilter Core Team

eth0: link up, 100Mbps, full-duplex, lpa 0x45E1

eth0: no IPv6 routers

The contents of /var/log/messages just has the same messages as above.  

Is Fedora ignoring my BIOS settings (onboard LAN disabled) and enabling it anyway?  It appears to assign eth0 to the RealTek RTL8139 chip.
