----------------------------------------
For a i386 Lenovo S10 Intel Atom n270 netbook, bisection indicates using
189a0ff3761b47 ... ix: Implement MSI-X support and enable multiple TX rings
locks up the machine on booting at the point:

...
md0: invalid primary partition table: no magic
Math emulator present
hptrr: RocketRAID 17xx/2xxx SATA controller driver v1.2
hpt27xx: RocketRAID 27xx controller driver v1.0 (Feb 28 2014 21:38:19)

Attached is a full verbose dmesg from the same machine running with master
previous to the above commit.  The machine only fully boots with
acpi disabled using hint.acpi.0.disabled=1, but even with acpi enabled the
lockup with the problematic commit occurs sooner than the normal lockup
with acpi enabled.  "Normally" on this machine booting with acpi halts at

acpi0.nexus0.root0
acpi0: <LENOVO CB-01> [tentative] on motherboard
ACPI: All ACPI Tables successfully acquired
ACPI FADT: SCI testing interrupt mode ...
ACPI FADT: SCI testing level/high
IOAPIC: irq 9, gsi 9 edge/high -> level/high
