Public bug reported:
-- Problem Description --
Some Power machines has limitations regarding INTx/Level-signaled interrupts in
some slots. The kernel will present currently the following message in dmesg:
"pci 0003:70:00.0: of_irq_parse_pci() failed with rc=-22"
This is an imprecise, and kind of "misleading" message. The following
patch improved the way this information is showed to user:
f1aa54840657 ("of/irq: improve error report on irq discovery process failure")
[https://git.kernel.org/torvalds/c/f1aa5484]
With the patch, messages will show like:
"pci 0003:70:00.0: no interrupt-map found, INTx interrupts not available"
"pci 0003:70:00.0: possibly some PCI slots don't have level triggered
interrupts capability" (<= this one shows only once, regardless the number of
slot without LSI)

So, we want to request Canonical to include the above patch on kernel 4.10, to
Ubuntu 17.04 (Zesty), if possible.
Thanks in advance,
Guilherme
