0.8.2 crashing (and wont start) when modprobe e1000e

2010-11-09 Thread Ma Begaj

hi,

I compiled 0.8.2 (kernel 2.6.37-rc1 vanilla) a few days ago and I just
saw that NetworkManager does not want to start if module e1000e is
loaded. And it crashes NetworkManager if it is already running. e1000e
(eth0) is working for me on the shell with i.e. dhcpcd and it worked
before.

Any ideas what could be causing this?

Thanks.

This is syslog right after I did "modprobe e1000e":

This gcc warning is actually very good: it shows a bug! Maybe even a
crash.  The bug is triggered when
g_udev_client_query_by_subsystem_and_name() returns NULL.

I did not really look at the code and missed the "goto"s, thanks
Mathieu for correcting me.

... and doing this puts the bug in a much brighter light: it makes gcc stop
on the initialization error instead of printing a mild warning.


The ideal code would look like this:
 
out1:
g_object_unref (parent);
out2:
g_object_unref (dev);
out3:
g_object_unref (client);
}

But Mathieu's bug fix is a bit less intrusive and probably good enough.
