I can reproduce it because I never lose sync when I don't access to /proc/.../temperature and when I access it, exactly at the same time, I lose the sync.

Subject: Re: [ACPI] SCI interrupt handler : spend too much time


Hi!

  
Since 2.6, when I read /proc/acpi/thermal/THR*/temperature and battery
info, my system spends too much time in SCI interrupt handler and it
loses the sync of my mouse, a synaptic. Any issue ?
    

Can you repeat it? Losing sync of mouse is probably a bug in inputs,
and should be fixed.
