Description of problem:
PC type: HP Compaq DX2000 MT
Ethernet controller: Intel Corp. 82562EZ 10/100 Ethernet Controller (rev 02)
Network card is correctly detected, both during first installation and reinstalling. Mii-tool and ethtool work, and link is detected, but the connection doesn't work anyway. Tried with DHCP and manual config. Tried with any speed/duplex combination, even forcing it on the switch port. Tried with Intel driver too. No success at all. With Ubuntu Linux 5.0.4 installed in another partition the card works perfectly!
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install FC4 from CDs
2. Boot the PC
3. Try to connect to the network
please attach the /etc/sysconfig/network-scripts/ifcfg-* files

Original poster configures the network card with dhcp from
system-config-network, and ifcfg-eth0 has the static IP settings. Possibly
related to bug 162648.
This is partially true, because in this case the default gateway is correctly set.
And even if I adjust manually the ifcfg-eth0 file, both for dhcp and manual
configuration, the network still doesn't work.
well, then it seems to be a kernel problem.
Have you tried booting w/ "acpi=off" on the kernel command line? If not,
please do so and post the results.
Also, please attach the output of running "sysreport"...thanks!

Wonderful! acpi=off makes the network work!
I have posted the sysreport output.
Antonio, thanks for the quick turn-around!
Unfortunately, success w/ "acpi=off" usually indicates a problem w/ the BIOS
of your machine. Often it is limited to IRQ routing, so you may want to try
also w/ "acpi=noirq" to see if that work as well. If so, you still should
have most ACPI capabilities available.
You may also want to check w/ your motherboard vendor to see if an updated
BIOS is available.
- acpi=noirq -> same problem
- upgraded kernel to 2.6.12-1.1390_FC4 -> same problem
- upgraded motherboard BIOS -> same problem
At boot start - without 'acpi=off' - I read:
Uncompressing Linux... OK, booting the kernel.
Irq 9: nobody cared!
handlers: [<c022f8df>] (acpi_irq+0x0/0x14)
Disabling IRQ #9
Well, I'm sorry... :-( Unfortunately, there isn't much I can do to improve
things for you.
Hopefully some later BIOS update will improve things for you -- you may want
to contact your BIOS/motherboard vendor to encourage them to make sure they
support Linux. Otherwise, "acpi=off" will remain your best bet.
Thanks again...I wish I could do more...
