Todays Next failed to boot on a Power6 JS22 blade with following oops.
      

Jiri, I suspect this might be your address list changes.

Although that's just a guess.  But please take a look.
    

Hmm, only thing I see might cause the problem would be if calling __hw_addr_add
in dev_addr_init fails, then dev->dev_addr would contain zeroes (which looks
this is not the case). But in this case the oops would appear earlier (in
ibmveth_probe dev_addr memcpy).

Will do the patch which checks the result to behave correctly in case of oom
but this imho this wouldn't help. Strange, I will dig into this more tomorrow.
  

I can recreate this problem with today's Next release as well. Let me 
know if you want me to try
out any thing to debug this problem.

Thanks
