Description deftunix 2015-02-06 12:05:47 UTC
FreeBSD 10.1 no detecs psm mouse on Dell Inspiron.
I seen that the problem was related to wrong I/O port allocation in ACPI DSDT.
PS2M has not port allocated in its CSR and mouse I/O port 0x66 is allocated by PS2K resources.

I patched BIOS DSDT and fix problem loading custom AML code using the loader tunables below:

acpi_dsdt_load="YES"
acpi_dsdt_name="/boot/dell_5748_deftunix.aml"

Booting FreeBSD in verbose mode in "/var/run/dmesg.boot" was entry:

psm0: unable to allocate IRQ

I'm experiencing the same problem regarding the (missing) psm(4) IRQ.
I discovered this while attempting to install
stable/13-n252407-f42139db639 on a Dell Inspiron 5755.
All attempts to get the trackpad to function fail. This
is how I discovered the "psm0: unable to allocate IRQ"
message in dmesg(8).
Linux and Windows both function properly. Linux discovers
and installs the necessary support for the trackpad (synaptics?).
Is there anything that I can provide to further assist in
tracking down and resolving this issue?

Thanks!
