[Bug 216558] New: networkmanager does not recognize network interface after module has been unloaded/reloaded
https://bugzilla.novell.com/show_bug.cgi?id=216558 Summary: networkmanager does not recognize network interface after module has been unloaded/reloaded Product: openSUSE 10.2 Version: Beta 1 Platform: Other OS/Version: Other Status: NEW Severity: Critical Priority: P5 - None Component: Network AssignedTo: rml@novell.com ReportedBy: seife@novell.com QAContact: qa@suse.de CC: hmacht@novell.com, thoenig@novell.com, behlert@novell.com OtherBugsDependingO 215208 nThis: simple testcase: #!/bin/bash dbus-send --system \ --print-reply \ --reply-timeout=2000 \ --dest=org.freedesktop.NetworkManager \ /org/freedesktop/NetworkManager \ org.freedesktop.NetworkManager.sleep echo "rmmod" rmmod r8169 sleep 3 echo "modprobe" modprobe r8169 dbus-send --system \ --print-reply \ --reply-timeout=2000 \ --dest=org.freedesktop.NetworkManager \ /org/freedesktop/NetworkManager \ org.freedesktop.NetworkManager.wake ################################################################ This is essentially the same what the now-cool pm-utils do during suspend. Unfortunately, network manager does no longer find a networking device after this. The only way to get it going again for me is a "rcnetwork restart". -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

FWIW, this works for me. Both my e1000 and my ipw3945 come back after resume. And I am doing the above steps (have pm-utils installed and have both modules reloaded on suspend/resume). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=216558 ------- Comment #3 from seife@novell.com 2006-10-31 06:09 MST ------- do you use pm-utils to suspend? you need to add your modules in /etc/pm/config and then call "pm-hibernate". However, my testcase fails without any suspend involved at all. I'll check the hal output. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=216558 ------- Comment #4 from seife@novell.com 2006-10-31 06:15 MST ------- ok. I did: lshal>/tmp/lshal.before bash /tmp/test.sh lshal> /tmp/lshal.after diff /tmp/lshal.* This is the diff: root@strolchi:~# diff /tmp/lshal.* 192c192 < battery.voltage.current = 12516 (0x30e4) (int) ---
battery.voltage.current = 12513 (0x30e1) (int) 1446c1446 < net.linux.ifindex = 15 (0xf) (int)
net.linux.ifindex = 14 (0xe) (int)
So this seems to not be the problem. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

I mean - the HAL code is known to be horrible wrt. performance and stuff - nm sees "no interface" - hal finally finishes detecting the interface - somehow, nm does not notice that there has turned up a new interface - nm never gets to know that there is a new interface. So i do not know who is to blame, but it surely does not work correctly. And no, i will not put "sleep 5" into the pm-utils scripts. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
