Using rawhide as of July 28.
All of a sudden, my ethernet won't come up. No link lights. But this is dual-boot machine, and networking works if I boot up Windows XP.
I've got a Realtek integrated card, and the kernel finds it:
lspci -vv
..............
02:03.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
Subsystem: Hewlett-Packard Company Unknown device 2a26
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR-
Latency: 64 (8000ns min, 16000ns max)
Interrupt: pin A routed to IRQ 21
Region 0: I/O ports at dc00 [size=256]
Region 1: Memory at fddff000 (32-bit, non-prefetchable) [size=256]
Capabilities: [50] Power Management version 2
Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=375mA PME(D0-,D1+,D2+,D3hot+,D3cold+)
Status: D0 PME-Enable- DSel=0 DScale=0 PME-
But no link light comes on at the linux machine, or at the router.
dmesg | grep eth0
eth0: RealTek RTL8139 at 0xffffc2000064a000, 00:15:f2:77:86:13, IRQ 21
eth0: Identified 8139 chip type 'RTL-8101'
eth0: link up, 100Mbps, full-duplex, lpa 0x45E1
eth0: no IPv6 routers present
NETDEV WATCHDOG: eth0: transmit timed out
eth0: Transmit timeout, status 0d 0000 c07f media 10.
eth0: Tx queue start entry 4 dirty entry 0.
eth0: Tx descriptor 0 is 0008205a. (queue head)
eth0: Tx descriptor 1 is 0008205a.
eth0: Tx descriptor 2 is 00082156.
eth0: Tx descriptor 3 is 0008204e.
eth0: link up, 100Mbps, full-duplex, lpa 0x45E1
Windows gets the dhcp address from the router. Fedora times out. I've tried setting Fedora to a static address, but then I still can't ping anything, including the router. OTOH, fedora gives no error about ifup'ing eth0 with a static address.
Completely puzzled. Don't know where or whether to file a bug report.

Have a look in /proc/interrupts at the number of interrupts related to your ethernet card, if it is broken out on its own line.
A box here on 2.6.23-rc1 did the same, with 0 interrupts on the IRQ assigned to the ethernet device, and adding pci=biosirq to the kernel commandline got it up again.

Thanks. I'll try that. I'll be gone for 3 days. For now I'm simply using Windows :(

That's... less than optimal... :-/
Please see bug #249950 [1] and #249857 [2]. These seem related. All of the mentioned symptoms go away with the 2.6.22.1-41.fc7 kernel that's in updates-testing now (see also comment #13 of bug #249857 [3]).

Hope this helps.
Cheers, Steven

For me 2.6.22.1-33.fc7 does the same thing as you describe, whereas 2.6.22.1-27.fc7 worked flawlessly.
