I've added

hw.pci0.13.0.INTA.irq="16"
hw.pci0.15.0.INTA.irq="17"
hw.pci0.5.0.INTA.irq="19"

and now it boots when ACPI disabled. I have also tried to move hints into 
/boot/loader.conf and this also works.

Now I have

hw.pci0.13.0.INTA.irq="40"
hw.pci0.15.0.INTA.irq="41"
hw.pci0.5.0.INTA.irq="43"

in /boot/loader.conf and I see the following lines in dmesg log:
em3: <Intel(R) PRO/1000 Network Connection Version - 6.7.3> port 0x5000-0x501f mem 0xd8400000-0xd841ffff irq 40 at device 0.0 on pci13
em4: <Intel(R) PRO/1000 Network Connection Version - 6.7.3> port 0x6000-0x601f mem 0xd8500000-0xd851ffff irq 41 at device 0.0 on pci15
em2: <Intel(R) PRO/1000 Network Connection Version - 6.7.3> port 0x4000-0x401f mem 0xd8320000-0xd833ffff,0xd8300000-0xd831ffff irq 43 at device 0.0 on pci5

that I plan to stick with.

I've replaced  src/sys/dev/usb/ehci_pci.c with revision 1.3 from trunk and 
now also reboot is handled well.

Thank you for all support and now I suggest to close the ticket.
We'll see if BIOS will be upgraded by Supermicro. For now, above workaround 
is the only cure for this and similar boards.
