I did boot with irqpoll, and indeed the unhandled interrupt does not occur,
but my understanding is that the irqpoll option is a temporary measure
(maybe to get past anotherwise fatal unhandled interrupt), but not a
permanent fix. (Because it is inefficient for the kernel to perform such
polling?
By the way, have you tried to boot with irqpoll as the kernel says ?
And i suppose you use wheezy according to your kernel (3.2.65) version, so
did you try to upgrade kernel from backport (3.16.7) ?

Thanks for your comment.
It turns out that unhandled IRQ16 happens irrespective of which USB port
the mouse is connected to, or even if the mouse is connected at all at the
time the system goes to sleep (in the latter case, when the mouse is
re-connected, it still shows the same lag). (I posted a
Hi,
Did the mouse lags occurs on all usb port ? Because you lspci return usb1
on IRQ16 and usb2 on IRQ23.
So if your problem is related to IRQ16, changing USB port might resolv the
problem. If the problem still there, i guess IRQ16 have nothing to do with
your mouse lags.

Sorry, I should have covered those questions in my original post!
It's a USB2 mouse, and no, unplugging/re-plugging it back in does not help.

What kind of connection for the mouse?
Does unplugging it and plugging it back in help?

When my computer returns from sleep, the mouse has a lag so severe that any
operation dependent on use of the mouse becomes all but impossible.
Looking at the kernel logs I found a message that seems to be related to
the problem described above; it's about an unhandled irq:
