But this patch isn't in 2.4.25-rc1 I have already problem with.

Now when linux.bkbits.net is working again, I walked through patches 
between 2.4.25-pre8 and 2.4.25-rc1 and reverted this patch -
http://linux.bkbits.net:8080/linux-2.4/cset%
401.1290.17.1?nav=index.html|ChangeSet@-9M

This solved problem for me, seems (tested only with 2.4.25-rc1 for 
now). I had feeling that it's related to multicast from the beginning 
because I couldn't reproduce panic when I hadn't ospfd daemon running 
(ospf uses multicast).
