Hmm, perf is taking up quite a bit of time to unwind stuff, more that I would expect. But other than libc (likely memcpy/memmove, perhaps apt-get install libc6-dbg and check), the only danger sign is the presence of acpi_os_write. Can you also look at sudo perf top --sort=dso (and install the dbg packages for the libraries you see there)?
