I lost my trackpad, psm0 is not longer detected (no dmesg messages about it, no device created). At that time in the boot it prints a couple plug'n'play related messages (see below). I just booted into my 7-stable kernel one more time and it's still there, it's really FreeBSD-8. The kernel config used for the two versions are identical when it comes to atkbd and psm. I have the /boot/loader.conf entry, irq 12 is not occupied by anything else. Here is 7-stable's opinion on the matter: ----------------------------------------- atkbdc0: <Keyboard controller (i8042)> at port 0x60,0x64 on isa0 atkbd0: <AT Keyboard> irq 1 on atkbdc0 kbd0 at atkbd0 atkbd0: [GIANT-LOCKED] atkbd0: [ITHREAD] psm0: <PS/2 Mouse> irq 12 on atkbdc0 psm0: [GIANT-LOCKED] psm0: [ITHREAD] psm0: model Synaptics Touchpad, device ID 0 ppc0: <Parallel port> at port 0x3bc-0x3c3 irq 7 on isa0 ppc0: Generic chipset (NIBBLE-only) in COMPATIBLE mode Here is the new output with 8beta4: ----------------------------------- atkbdc0: <Keyboard controller (i8042)> at port 0x60,0x64 irq 1 pnpid PNP0303 on isa0 atkbd0: <AT Keyboard> irq 1 on atkbdc0 kbd0 at atkbd0 atkbd0: [GIANT-LOCKED] atkbd0: [ITHREAD] unknown: <PNP0c02> can't assign resources (memory) unknown: <PNP0680> can't assign resources (port) unknown: <PNP0680> can't assign resources (port) uart0: <16550 or compatible> at port 0x3f8-0x3ff irq 4 pnpid PNP0501 on isa0 uart0: [FILTER] ppc0: <Standard parallel printer port> at port 0x3bc-0x3c3 irq 7 pnpid PNP0400 on isa0 ppc0: Generic chipset (NIBBLE-only) in COMPATIBLE mode >How-To-Repeat: Probably need a thinkpad r40 to reproduce, but I can run whatever test code you like. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
