Hi

I'm in the process of setting up Alpine 2.0 as my main router/firewall.

It's my first hike into "The Alps", so there's a lot to get used to, but
overall I do like it :)

Fortunately for me, I have two 4801's so I'm in a position to test stuff
before I commit the system on the actual firewall hardware... which turns
out to be very lucky indeed...


The long story short:

Booting the 2.6.32.18 kernel with the default parameters on the soekris
results in a kernel panic.

After trying out the kernels of alpine 2 beta-* and rc-* I found that:

2.6.32.15 boots ok
2.6.32.16 upwards 'panic'

After searching the web I found a hint that 'noreplace-paravirt' had worked
for someone else. So I tried adding that to the append line in syslinux.cfg
- and lo and behold: Now the kernel boots :)


So far so good, except now I get:

pci 0000:00:07.0: BAR 6: address space collision on of device
[0x3f000000-0x3f00ffff]
pci 0000:00:08.0: BAR 6: address space collision on of device
[0x3f000000-0x3f00ffff]

- which I'm somewhat unhappy about, since those are two of the three onboard
NICs :(
(Incidentally the 2.6.32.15 kernel also has these collisions)

The thing is that this system is going to be pretty 'complicated', with a
bunch of vlans, and I'll be needing the NICs.


I'm not too sure how to proceed from here?

Do any of you have insights/experience about this kind of issue?

>From what I've read so far, it may be related to:
https://patchwork.kernel.org/patch/39988/ and symptoms range from 'more or
less cosmetic, no real problems' to 'complete system lockup'.

Obviously I'm not too thrilled by the prospect of the latter potentially
happening to my firewall... :P


I have a serial console on the box, so it's pretty esay for me to 'grab' the
output. In fact I've saved the output from booting the various kernels (with
various kernel parameters) but I've nowhere public to put them ATM.

They're about 7K-9K each. If anyone's interested, let me know?
