[parisc-linux] kernel crash with IPv6

[Helge Deller]

Just got a kernel crash with our git tree code.
Not sure if this is generic problem or related to parisc.
I didn't investigated any further. 
Just reporting her in case someone has an idea.
IPV6 and serial console were enabled.
Turning IPV6 off fixed it for me.
