Message-ID: <20060109040606.118a0d33.akpm@osdl.org> (raw)
While doing a binary search for a buggy patch (it was
gregkh-pci-x86-pci-domain-support-the-meat.patch, reported on
linux-kernel), I hit the below.

I don't think the PCI domain patch is the cause of this - it's just the
thing which cause the abort handler to run. I'd be suspecting that the
aix7xxx abort handling is bust. I seem to recall seeing someone else
report this a month or so ago?
