Lombard hard freeze (update: mem>64MB)

[Gabriel Ricard]

Well, if we're gonna do some controlled tests we
should all probably start out with the same kernel to
begin with. Which one is the latest greatest stable
version? I suppose we should all test with the exact
same kernel config, so if someone wants to put their
kernel, system.map, and modules up on an ftp site so
we can all start with that kernel, I could start
testing diff. configs on my PB immerdiately. :)
