I'm not sure what you mean by 'the ALSA version'.  ALSA is made up of
kernel drivers and libasound in user-space.  The drivers are included in
the kernel package and cannot be incompatible with it.  The interface
between the drivers and libasound is not supposed to change in an
incompatible way, and in any case a user process should not be able to
crash the kernel.

So I think this is just a bug in the driver.  Please report it upstream
at <https://bugzilla.kernel.org> under product 'Drivers', component
'Sound(ALSA)'.  Let us know the bug number or URL so we can track it.

I don't see any LIRC modules in the list of loaded modules.  This may be
a bug in the lirc package.  In any case, you need to make a separate bug
report for each bug.
