I'm not sure if this is a Dell BIOS problem, new interrupt code problem, or PS/2 device driver problem. The Dell 5150 laptop has a Synaptic touchpad, which fails to attach with the GENERIC kernel from RC1 and a custom kernel from today sources. A verbose boot shows: atkbdc0: <Keyboard controller (i8042)> port 0x66,0x62,0x64,0x60 irq 1 on acpi0 atkbd0: <AT Keyboard> flags 0x1 irq 1 on atkbdc0 atkbd: the current kbd controller command byte 0065 atkbd: keyboard ID 0x41ab (2) kbd0 at atkbd0 kbd0: atkbd0, AT 101/102 (2), config:0x1, flags:0x3d0000 psm0: current command byte:0065 psm0: the aux port is not functioning (-1). Note, the psm0 messages are unchanged with/without acpi and with/without apic compiled into the kernel. After looking through psm.c, I added hint.psm.0.flags="0x1000" # Ignore error in Aux Port test to /boot/device.hints. A verbose boot shows: psm0: current command byte:0065 psm0: <PS/2 Mouse> flags 0x1000 irq 12 on atkbdc0 psm0: model Generic PS/2 mouse, device ID 0-00, 2 buttons psm0: config:00001000, flags:00000000, packet size:3 psm0: syncmask:c0, syncbits:00 and moused(8) seems to be happy. I haven't looked closer at the problem, yet. However, with the impending release of 5.2, an erratum may be in order. -- Steve
