Test Results with adeos-ipipe patch:
H/W Setup is same, S/W Changed to adeos-ipipe with 3.0.8 kernel.
adeos-ipipe-3.0.8-powerpc-2.13-04.patch applied to 3.0.8 kernel,
spurious interrupt is not raised with this patch.
I still don't know what ppc platform you are running on, which does not
allow me to figure out which interrupt controller might be involved, and
how to try reproducing this issue.
Again and I won't ask for this once more:
- what is your ppc platform: 40x, 44x, 52xx, 82xx, 83xx, 85xx, 86xx,
anything else?
I need the cpu type _and_ the board type. Attaching your kernel .config
would provide the required information.
CONFIG_PCI_MSI as found in your configuration won't work, with any past
or current pipeline release for powerpc (3.0.8 was certainly a fluke, or
MSI was disabled there). The IRQ chip handlers are still attempting to
mask the MSI source upon interrupt, which won't fly in the I-pipe case.
