[parisc-linux] HPMC 2.6.5-rc1 kernel on c3k

[parisc-linux] HPMC 2.6.5-rc1 kernel on c3k

[Grant Grundler]

FYI.

My c3k HPMC'd last night when I was compiling kernels.
USB was likely just the "victim" and not the culprit since
I was working remotely and wasn't using any USB devices.
Ie recent changes to SBA IOMMU code might still be suspect
(I have no ideas what, just it's the place to start looking).

I've typed in console output by hand so it may not be 100% accurate.

hth,
grant

Just in case, with the same kernel, I got the same kind of pb on the c110
since ccio-dma was changed. Unfortunately I don't have enough time the week-end
to help more.
