I made two experiments to verify: a) acpi compiled into kernel (not loaded as a module), puc and uart in kernel (as before) b) acpi as a module (as before), puc and uart as a module (loaded via /boot/loader.conf) Indeed in both cases I now see dev.uart.0.%desc: 16550 or compatible dev.uart.0.%driver: uart dev.uart.0.%location: handle=\_SB_.PCI0.IBRG.COM1 dev.uart.0.%pnpinfo: _HID=PNP0501 _UID=1 dev.uart.0.%parent: acpi0 dev.uart.0.wake: 0 dev.uart.1.%desc: 16550 or compatible dev.uart.1.%driver: uart dev.uart.1.%location: handle=\_SB_.PCI0.IBRG.COM2 dev.uart.1.%pnpinfo: _HID=PNP0501 _UID=2 dev.uart.1.%parent: acpi0 dev.uart.1.wake: 0 You are right, there is a cosmetic issue if acpi is loaded as a module, but uart is not. I'd say it is cosmetic, as the on-board UARTs (0 and 1) have been working fine in either configuration, whether attached to acpi0 or to isa0. I have problems with the dual UART PCI board. These are still dev.uart.2.%desc: 16550 or compatible dev.uart.2.%driver: uart dev.uart.2.%parent: puc0 dev.uart.3.%desc: 16550 or compatible dev.uart.3.%driver: uart dev.uart.3.%parent: puc0 in either case. >It's not necessarily a problem if you have the right hints, The delta between my device.hints is this: --- device.hints~ Thu Jul 14 20:42:19 2005 +++ device.hints Mon Nov 27 07:30:37 2006 @@ -34,13 +34,13 @@ hint.vt.0.disabled="1" hint.apm.0.disabled="1" hint.apm.0.flags="0x20" -hint.sio.0.at="isa" -hint.sio.0.port="0x3F8" -hint.sio.0.flags="0x10" -hint.sio.0.irq="4" -hint.sio.1.at="isa" -hint.sio.1.port="0x2F8" -hint.sio.1.irq="3" +hint.uart.0.at="isa" +hint.uart.0.port="0x3F8" +hint.uart.0.flags="0x10" +hint.uart.0.irq="4" +hint.uart.1.at="isa" +hint.uart.1.port="0x2F8" +hint.uart.1.irq="3" hint.sio.2.at="isa" hint.sio.2.disabled="1" hint.sio.2.port="0x3E8" There are no specific hints for the puc-based UARTs. I understand that PCI devices don't need such hints. Actually, both the "sio kernel" and the "uart kernel" locate the device identically on the same IRQ and IO ports. Am I mistaken here? >Why do you have PUC_FASTINTR for sio, but not for uart? I had just been trying to play with the knobs that I have in the config file. PUC_FASTINTR reduces overruns somewhat for the "sio kernel" but it doesn't change behaviour at all. Specifically, no impact on this issue.
