It's not that initialisation fails (I'm booting the kdump kernel with
pci=nomsi, however, I also tried without). The problem is that the
kernel gets interrupts from this device where it was not configured.
SAPIC interrupts are disabled before shutdown, but not MSI interrupts.

However, that patch addresses only the issue to disable interrupts
before the cciss driver re-enables the interrupts again. When that
happens, there could still be a problem because the device is in an
invalid state.

The firmware vendor seems to work on a fix to support the reset
message. So I think we can ignore this issue here for now.

Yes. :(
