DaveM: do you mind if I submit a patch to change the default for sparc
to SLUB?
I think we're jumping the gun about all of this, and doing anything
with default Kconfig settings would be entirely premature until we
know what the real bug is.
The suggestion to change to SLUB as the default was based on Linus'
comment "SLAB is probably also almost unheard of in high-CPU
configurations, since slub has all the magical unlocked lists etc for
scalability."
On my T4-2 I've used nothing but SLAB and haven't hit any of these
problems. I can't even remember the last time I turned SLUB on,
and it's just because I'm lazy.
Interesting. With -j <64 and talking softly it completes. But -j 128 and
higher always ends in a panic.
