Bug Description
I am using Dapper FL5, latest upgrades applied, kernel 2.6.15-18 (-k7 or -386) on an Averatec 3250-HX1 laptop with mobile AMD Athlon(tm) XP-M (LV) 2200+ processor.
Problem: Ubuntu desktop does not have network functionality, system hangs completely when attempting dhclient from command line (becomes unresponsive, can't access a console via Ctrl-Alt-F1, can't restart GDM via Ctrl-Alt-Backspace) or trying to reactivate the eth0 interface via System > Amdministration > Networking.
This worked fine in previous Ubuntu version (5.10). Ethernet controller is VIA Technologies, Inc. VT6102 [Rhine-II] (rev 74) as reported by lspci.
When booting in recovery mode, networking works fine, that's how I was able to apt-get update / upgrade.
I tested using -k7 -386 kernels with the same results.
When checking the dmesg output of a normal boot (not recovery), I see this:
[4294703.809000] irq 11: nobody cared (try booting with the "irqpoll" option)
I tried the irqpoll option in the boot options but the system hangs before getting to gdm, with continuous HD activity.
I also found this in dmesg:
[4294703.809000] Disabling IRQ #11
Searching with different terms in Google ("Disabling IRQ #11", "irq 11: nobody cared") this seems to be reported in other distributions and may be related to ACPI. A closer example from the Averatec forums lists a possible workaround which I haven't tried, as I haven't had time to do it:

I am attaching different commands output for -k7 kernel normal and recovery boot.
