Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

This is a little old thread but I have exactly the same problem (happened after video card install) and don't know what to do. Tried recompiling kernel without any ACPI/APM features and network still keeps dying.
Tried append=pci-noacpi - nothing.
BTW what is the difference between ACPI and APCI and who of them is the bad guy here?
I'd like to join the club. I'm now getting this error as well, seemingly randomly on my Fedora7 webserver. From what I've read, it sounds likely that it may be due to having just upgraded my router to 10/100/1000.
Here's the log I'm seeing:
Sep 12 08:26:40 localhost kernel: NETDEV WATCHDOG: eth0: transmit timed out
Sep 12 08:26:40 localhost kernel: sky2 eth0: tx timeout
Sep 12 08:26:40 localhost kernel: sky2 eth0: disabling interface
Sep 12 08:26:40 localhost kernel: sky2 eth0: enabling interface
Sep 12 08:26:40 localhost kernel: sky2 eth0: ram buffer 0K
Sep 12 08:26:43 localhost kernel: sky2 eth0: Link is up at 1000 Mbps, full duplex, flow control both
This is my network card:
02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8056 PCI-E Gigabit Ethernet Controller (rev 12)

Reason: added network card
I finally solved (worked around) this (netdev watchdog timeout, eth0 kaput) problem (Fedora Rawhide, built-in network card 8139too, K8V800M motherboard) by appending noapic to the end of the kernel line in grub.conf
not "noapci" (whatever the heck that is)
Works for me, at least until somebody figures out a real solution.
It also stopped my video card from generating Xid errors. Seems IRQs are a bit tangled on this board.
i have the same problem.
i solved it by enabling "Onboard Lan Boot ROM" in the BIOS.
Integrated Peripherals -> Onboard Device -> Onboard Lan Boot ROM
my chip is realtek rtl8100c (onboard).
it works now.
the "Lan Boot ROM" can initialize the chip correctly but linux driver not, i guess.
it works all the time in windows no matter whether "Onboard Lan Boot ROM" is enabled or disabled.
will try doing this as i am facing the same issue over and over again,
the error that i am getting is with regard to the usb0.
thanks for the help. will keep posted on the same.
NETDEV WATCHDOG: usb0 (cdc_ether): transmit queue 0 timed out

I partially disabled ACPI in the kernel (not APIC, these are two different things not a typo,) by entering the following line in my /etc/lilo.conf
append = "pci=noacpi"
Since then I have not (yet?) had a recurrence of the problem.
