Description holger.gleissner 2010-05-12 14:25:01 UTC

After (properly) upgrade from baselayout-1 to baselayout-2 (-2.0.1) with openrc-0.6.1-r1 the system hangs when i want to reboot or shutdown. The system is actual, the special is, that the system is a nfs-root mounted system. I have re-emerged baselayout-2 and openrc but without success.


Reproducible: Always

Steps to Reproduce:
1. upgrade the system to baselayout-2 from bsaelayout-1
2. reboot the system

Actual Results:  
the system hangs and error messages "...Speicherzugriffsfehler..." (...Memory access error...) appears

Expected Results:  
the system will shutdown/reboot properly without errors

AFAIK there are two things you need to change:

1) Edit /etc/init.d/nfsmount to not run the umount command in stop().
2) Edit /etc/conf.d/network and set ifdown_eth0="true" so that the default `ifconfig eth0 down' command isn't run.

Assigning because we'll ultimately need to document this somewhere[1].

Thanks for the help!
The Edit in 1) works good.
The Edit in 2) has no effect, the error messages are the same as before:
:::
* Bringing down interface eth0
/lib64/rc/rc-functions.sh: Zeile 43:  4400 Speicherzugriffsfehler mountinfo
--quiet --netdev "$1"
/lib64/rc/rc-functions.sh: Zeile 43:  4401 Speicherzugriffsfehler mountinfo
--quiet --nonetdev "$1"
* Stopping dhcpcd on eth0 ...
====> System hangs

In /etc/conf.d/network are only comments excluding the Edit in 2). I have also tested and created an empty File /etc/ifdown.eth0 but with the same result.
