Chen,
Please boot with "acpi=off" and attach the output from dmesg -s64000
and paste in the contents of /proc/interrupts
and report if the sky2 is working or not.
Also, if you rmmod the driver and then load it again, as suggested
by Scott, does the problem go away?
Can you answer Shaohua's question?

Stephen,
XT-PIC mode is independent of level vs. edge triggering.
LAPIC mode is independent of level vs. edge triggering,
> Local APIC disabled by BIOS -- you can enable it with "lapic"
BTW. It is usually a very bad idea to over-ride the BIOS on this.
Indeed, it is usually such a bad idea, that this line should
probably be removed from the kernel to not tempt people.
Stephen, What is the interaction between ohci and the NIC that you've
see as an issue in the past? Chen, A simple way to to prevent the
X module from loading is to find it under /lib/modules X.ko, gzip it
and reboot.
Here is the failing device:
> lspci -vv
01:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8036 PCI-E Fast
Ethernet Controller (rev 10)
Interrupt: pin A routed to IRQ 11
> failing dmesg
ACPI: PCI Interrupt 0000:01:00.0[A] -> Link [LNKA] -> GSI 11 (level, low) ->
IRQ 11
PCI: Setting latency timer of device 0000:01:00.0 to 64
sky2 v0.15 addr 0xcc000000 irq 11 Yukon-FE (0xb7) rev 1
sky2 eth0: addr 00:a0:d1:21:5b:e1
> working dmesg
ACPI: PCI Interrupt 0000:01:00.0[A] -> Link [LNKA] -> GSI 11 (level, low) ->
IRQ 11
sk98lin: Network Device Driver v8.31.2.3
(C)Copyright 1999-2006 Marvell(R).
In both cases, the device is using IRQ11. Unclear why sky fails
and sk98lin works. Maybe sk98lin is doing some polling and sky is not?
Both cases share the serious issue that IRQ10 is broken:
irq 10: nobody cared
This could happen if the NIC registers on IRQ11, but is really
pulling on IRQ10.
(shot in dark) Any change if you boot with sky2.disable_msi=1
