Bugzilla Bug 143887

Upgrading baselayout from 1.12.1 to baselayout-1.12.4-r{2,3} breaks my system
in a major way.

Please see the screenshots, one is mine, one somebody elses, see
http://forums.gentoo.org/viewtopic-p-3510819.html#3508596 for original forum
posting about the problem:

What happens is that trying to stop the net.eth1 service (eth1 is my ipw3945)
gives my system a kernel panic. The "process metalog" string in the panic dump
seems to be non-relevant as the it seems to be entirely random each time and
could be "ksoftirqd/1" just as well as any other. 

Reverting back to baselayout 1.12.1 fixes the problem. This happens both on
current stable ipw3945* packages as well as keyword-masked ones. I tried
various 2.6.17.* and 2.6.18-rc* vanilla kernels, none helped.

Here my emerge --info:

The second screenshot link is for my compy :D
I have found that shutting down services in this order works:

net.eth1
ipw3945d
the rest of the system.

Add this to /etc/conf.d/net.eth1

RC_NEED="ipw3945d"

That seemed to do it.

I'll take care of that when I find some time to fix all pending ipw3945 bugs.

> Add this to /etc/conf.d/net.eth1
> RC_NEED="ipw3945d"

This causes errors (about missing ipw3945 service) on my setup. And doesn't
even start the card properly.

How is it supposed to work?

Strange. What versions of related packages are you using? No errors upon
starting your system up?

I am using the service listed here:

Well, that's not a perfectly kosher solution I think. Will stick with
baselayout-1.12.1 until this gets resolved properly.

Hey, can I be of any help in solving this bug? I have the hardware so I can
test possible solutions and report. This is pretty crucial to me and I'd be
willing not to wait indefinitely for a solution.

The solution offered is the best I have at the moment.
AFAIK the ebuild doesn't provide an init script or anything like that atm and I
don't have the hardware to test.

This should be fixed now with 1.7.22-r2 in portage. Feel free to reopen if the
issue isn't fixed for you.

Problem is not solved. The new init script improperly starts the daemon.

No its not fixed.
I'm using baselayout 1.12.6 and the kernel panic is still there. Might be a
slightly different use case since I'm using wpa_supplication.

I've added the line RC_NEED="ipw3945d" to /etc/conf.d/net.eth1 (is this
correct?), but it has no effect. I notice that eth1 is stopped before ipw3945.

During shutdown:

*      Stopping dhclient on eth1 ...
*      Shutting down eth1 ...
*      Stopping wpa_cli on eth1
