This is most likely the problem as com started attaching over acpi in
7.1. The corresponding acpi entries looks sane from what I can tell.
Maybe comprobe1() must be used in dev/acpi/com_acpi.c after all, just
like dev/isa/com_isa.c already does.
Device (COM1)

Method (_STA, 0, NotSerialized) // _STA: Status
{
Local0 = CAEN /* \_SB_.PCI0.ISA_.CAEN */
If ((Local0 == Zero))
{
Return (Zero)
}
Else
{
Return (0x0F)
}
}
Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings
{
IO (Decode16,
0x03F8, // Range Minimum

}
Device (COM2)
