Re: [uml-devel] 2.6.7-1: ifconfig kernel panic

["shigekazun@yahoo.co.jp" <shigekazun@yahoo.co.jp>]

Resolved by 'random' patch.

  kernel-source-2.6.7 <http://packages.debian.org/kernel-source-2.6.7>
+ uml-patch-2.6.7-1 <http://www.user-mode-linux.org/mirror/uml-patch-2.6.7-1.bz2>
+ random <http://user-mode-linux.sf.net/work/2.6/2.6.7-1um/random>

Now 'ifconfig' works fine.

ns:~# ifconfig
eth0      Link encap:Ethernet  HWaddr FE:FD:C0:A8:88:C8
          inet addr:192.168.136.200  Bcast:192.168.136.255  Mask:255.255.255.0
