Debugging memory allocation

[Adrian M. <ad...@ne...>]

I don't know if this is just G2 flakiness, but if I start playing sound
and then start hotplugging devices then I will sometimes get this sort
of oops (these don't down the system but they can make it unstable) -
any clues as to what might be the issue (these are now quite old -rc2?
kernels...)... just wondering if anybody can see anything obvious?

A recursive oops even, great. Write-through works fine on all of my 2-way
and 4-way set associative dcaches, you're probably the only user of
direct-mapped SH caches these days. I'll see if I can dig up a board with
a direct-mapped cache or see if this is reproducable with EMODE disabled
on 2-way.

Does disabling the dcache work for you?

(2.6.23 + Linus's git and your git of about 48 hours ago). .config at
end... will now investigate other cache options
