removing libata modules and rebooting fixes it - so it seems to be 
loading of libata.
Can you please cherry-pick:

commit b1f9e5e355e9 ("ide: fix IRQ assignment for PCI bus order probing")

from mainline and let us know if that solves the issue ?
No, still breaks the same way (b1f9e5e355e9 patched on top of 
0e4c2eeb758a).

4.14.0-rc5-00095-g1c9fec470b81 was also still broken the same way (tried 
on Sunday).
I am not sure I patched the right sys file but if I did, does the patch
below help ?

I think that at sata driver binding time the kernel finds a freed
pointer in the host bridge map_irq() hook and that's where things
go wrong.

Please let me know if that's the right sys file, it is a mechanical
change and making it for other sys file should be reasonably simple.

"Booting GENERIC on Tsunami variation Webbrick using machine vector 
Webbrick from SRM"

Seems to be the correct file - tsunami is referenced from this file and 
the IRQ-s are DP264.

But the patch does not make a difference :(
