Comment 18 for bug 12124

I've seen similar behavior as that described in the initial bug report message
on a laptop that had a buggy ACPI BIOS. When the Gnome battery applet was
running and polling the battery status every 5 seconds, it would apparently drop
pointer and keyboard interrupts. It was as if the ACPI BIOS routines had the
interrupts locked out and took too long to run. There was always messages about
the synaptics pad resyncing in the kern.log and dmesg. Upgrading the BIOS and
reducing the battery status polling frequency fixed the pointer warps and
extraneous button events.
