xl device doesn't work with ACPI enabled under -current and -stable
I have a 3C905C network card (xl driver) which worked perfectly with
ACPI enabled under 12/22/2004 -stable (ISO downloaded from
after I upgraded my system to -stable last week, xl doesn't work anymore
with ACPI disabled (not packets can go out or come in).
Today I upgraded -stable to -current and rebuilt everything, but xl0
still didn't work. Whenever I do any network related work (ping, ssh),
the following kernel messages always came out:
xl0: watchdog timeout
intr 3 at 1811 hz, removing livelock limit
intr 3 at 103321 hz, livelocked! limiting at 20000 hz
Here is my network card:
xl0@pci2:0:0: class=0x020000 card=0x00e31028 chip=0x920010b7 rev=0x78
vendor = '3COM Corp, Networking Division'
device = '3C905C-TX Fast EtherLink for PC Management NIC'
class = network
subclass = ethernet

If I boot the system with ACPI disabled, then everything works again.
Any ideas why?
I will provide more information if needed.
