Re: Frequent Oops on Shutdown 2.6.10

[AndyLiebman@aol.com]

Hello, Yoshi

Should I bother to apply  this patch, or should I wait for you to make this 
last change? What did you  think about my comment that the Oops only occurred 
when the Ethernet cable had  been unplugged during operation? 

Regards, 
Andy Liebman

Thanks, this looks great.  There is just one technical  detail
to patch up.

You need to check whether icmpv6[0] is NULL either  here or in
snmp6_mib_free.  Otherwise when snmp6_alloc_dev fails  we'll
wind up here and then call free_percpu on a pair of NULL  pointers.
