Hi all,
I just tried Linux 4.6.0-rc7 with qemu 2.6.0-rc4. Same error and
behaviour. What the heck is this?
Could you post 'sudo lspci -vvvs 01:00.0' from the host system? I
found possibly something more similar to your card and it has rather
poor alignment of the MSI-X structures, I wonder if your issue is
something similar. Unfortunately this HBA hosts the root disk on
the system I found, so I can't assign it unless I can figure out
something else to run the host from (and I don't have physical
access to run from USB).
I have a similar piece of hardware (it's the LSI branded card instead of
the IBM, but the chip is the same). Attached is the lspci output from
it, for comparison if nothing else. Unfortunately, this is also hosting
my root filesystem, so I haven't had a chance to use it with a VM yet,
so I can't say if it would work.
