Is a copy of the oops output available?

Is there any possibility of testing a more up-to-date kernel?

Thanks.

	I don't see any errors when adding a VLAN approximately as
described above when running 2.6.25-rc4.  I say approximately because
the steps must be performed in a different order than shown, but adding
a VLAN to a slave that's up and promisc isn't generating an error for
me.
