Hi,

my touchpad has been working like a charm until recently, then I
noticed psm0 didn't exist any more.
A verbose boot shows the following message in dmesg:

% jarjarbinks:~:107# dmesg | grep ^psm
% psm0: unable to allocate IRQ
% psmcpnp0: <PS/2 moudr port> irq 12 on acpi0
% psm0: current command byte:0047
% psm0: strange result for test aux port (1).
% psm0: failed to reset the aux device

Therefore, I added PSM_CONFIG_NORESET (0x400) to hint.psm.0.cflags
in loader.conf(5) and this made psm0 come back and the touchpad work.

I tried older kernels back to 2006.03.01 but none made my touchpad
work without this flag.

Does anyone have an idea of what has happened to my laptop ?

Thank you.
