Subject: multipathd: BUG: unable to handle kernel NULL pointer dereference
Date: Tue, 22 Jan 2013 11:19:50 +0100	[thread overview]
Message-ID: <20130122111950.149768tojz4wvgzq@webmail.idowa.de> (raw)

Hi,

I've got SuSE 11.4 running multipath tools compiled from git.
It looks like I've got the same problem as described here:  
http://www.spinics.net/lists/dm-devel/msg17038.html

What is the status on this issue?
