This should still have one?
There is a boot option (I do not find it in kernel-parameters?), to keep the console up during suspend/resume.
You might want to increase the ACPI output first:
echo 0x1f >/sys/module/acpi/parameters/debug_level
or even (can be a lot output):
echo 0x21f >/sys/module/acpi/parameters/debug_level

Then suspend and check the last lines it executes you see on serial console (with this boot param to not disable serial) when it freezes. If it points to ACPI, attach acpidump output of the system. Rafael/Pavel might want to correct/enhance my comments.

BTW: Is this possibly related to a Docking station?
