[parisc-linux] bad loopback error msg

[Grant Grundler]

Hi,

Helped someone install 0.9.2 on a B180 (serial console) and following
the instructions, basically got it up and running.  He needed some help
with setting up apt (pointing to HP internal mirror).

But I couldn't figure out what was causing the following error msg
to get printed on the console every minute or so:

    ip_local_deliver: bad loopback skb: PRE_ROUTING LOCAL_IN 
    skb: pf=2 (unowned) dev=lo len=328
    PROTO=17 0.0.0.0:68 255.255.255.255:67 L=328 S=0x10 I=0 F=0x0000 T=16

Any ideas?

This B180 is up-to-date but still running 2.4.0-32 vmlinux
(original kernels from 0.9.2 I think).

Um, I think that's fatal.  You should upgrade the kernel before upgrading
glibc, or you may run into problems.

I got the same error when I originally installed 0.9.2

A 2.4.9-paxx kernel solves this.  I was able to update
the glibc and compile a new kernel with this error (setting the
log level to two with SysRq helps to filter out all of the
errors though).

I think this is caused by dhclient being automatically run from
init scripts, even though you have specified a manual network config.
rm /etc/rc?.d/*dhclient or similar should help.  dhclient should
only be invoked via ifup/ifdown, but earlier versions installed
rc scripts as well.

Got exactly the same on 712/100 (STI).
After I did: "ifconfig lo down" those messages did clobber my screen again
Perhaps a overkill, but it works..
