The source? :)
Or ask here or ask Google on a case-by case basis.
"IRQ #: Nobody cared" means, I believe, that the CPU received an
interrupt that wasn't accepted by a driver. I'm not certain under what
circumstances this will happen, but it's generally not dangerous in
the slightest.
"<pointing device> lost synchronisation" is the case where the
serial data stream coming from the pointing device (mouse, touchpad,
etc) has had a problem, and it's lost track of where in the data
stream it is. PS/2 mouse protocols (for there are a great many) are
serial protocols, and involve variable length data groups. If a group
is sent which the driver doesn't know how to deal with (i.e. doesn't
know its length), or it misunderstands a group and thinks it's a
different length, then it can get out of sync with the protocol stream
from the device. In this case, it tries to regain synchronisation by
dropping bytes from the stream. If this happens only occasionally,
then you've probably just hit a bit of corruption on the cable. If it
happens constantly, then you've probably got the wrong protocol for
the device.
