>Description:
Begining with "src/sys/dev/pci/siisata_pci.c" r1.17, MSI is enabled.
While this appears to be fine for everyone else, on my siisata(4)-
equipped machine, it causes the disks attached to it to fail to be
identified/attached.

This was reviously logged in kern/54289, but is now seen to be a
different issue.

The relevant exerpt from a success:

siisata0: interrupting at ioapic0 pin 19
siisata0: SiI3124, 3.0Gb/s
siisata0: 32-bit 66MHz PCI
>How-To-Repeat:
Build a kernel from sources of 22-Oct-2018 21:00 UTC or later (includes
r1.17 or later of "src/sys/dev/pci/siisata_pci.c") and boot on machine
equipped with SiI3124 card.

May depend on host system, as there has been a report in kern/54289
that it works fine for at least one person.
>Fix:
Workaround:

Revert "src/sys/dev/pci/siisata_pci.c" to r1.16 and rebuild.

With this, I can finally boot netbsd-9 on my file server and have it
see the first four disks in my RAID.

I committed the MSI change, I'll look into this. Can you please include
the pcictl dump for the device? It may be there is more than one MSI vector,
and the device triggers different MSI interrupts according to channel.

 For further testing, I'll build test kernels from HEAD (r1.20 of
 "src/sys/dev/pci/siisata_pci.c" at this time).  I am otherwise running
 a 9.0_STABLE kernel with that file rolled back to r1.16.

 Some if not all siisata(4) parts support multi-vector MSI.  But I don't
 think I enabled it, and I should think the chip/channel resets we do
 would put it in a single interrupt mode.

 This particular card is not even multi vector.

 I have just the PCI Express one (Adaptec 1220A with SiI3132 chip), and
 it works fine with MSI.

 I think it's unlikely it's board problem (wm0 is using MSI and works),
 but perhaps worth checking if by change there would be any BIOS
 settings enabling MSI just for particular slots.

 Another option would be to simply disable MSI for Sii3124. It's an old
 chip used for old PCI/PCI-X cards, so not much of those left in wild.

 In case it's relevant, the host also has a PCIe wm(4) ethernet card,
 i82574L and it uses MSI without issue.

 The siisata card is a 1x PCIe card but is installed in a 16x slot (that
 would commonly be used for a video card, but this machine has built-in
 intel video hardware).  The wm(4) card is a 1x PCIe card installed in
 a physical 1x slot.

 I mention this as I have seen problems with non-video cards being
 mis-identified when installed in the 16x PCIe slot.  (A 2-port wm(4)
 card in the 16x slot of a Dell OptiPlex 760 was mis-identified as an
 SDVO device by the machine's BIOS and couldn't be netbooted and didn't
 show up in dmesg when booted from local disk.)

 I wrote nearly the same thing before I saw this message.

 I'll take a look when I next get a chance.

 That explains a lot.  I should have included more in the relevant snippet
 of dmesg.  My SiI3124 is a 1x PCIe card, but it's the PCI/PCI-X chip behind
 a PCIe-PCI reverse bridge:

 [...]

 No BIOS settings for MSI.  The only PCIe setting was for "test pattern"
 IIRC and it was set to enabled.

 Following some recent changes to MSI handling, I booted a -current
 kernel to see if it had any positive impact on the issue in this PR.

 Unfortunately it does not.  Disks attached to the siisata(4) card,
 while they attach, are inoperable, just as described originally in
 this PR.

I've disabled MSI for SiI3124. Can you confirm it works with rev. 1.21
of sys/dev/pci/siisata_pci.c ?

 Log Message:
 disable MSI for SiI3124 - interrupts don't seem to work on this old board
 when MSI is enabled, maybe because it's behind a PCI bridge
