please check  /proc/sys/vm/min_free_kbytes after reboot.
If it does not contain 16386, please do a chmod +x /etc/rc.local. Several people have
reported that doing this solved the problem for them (until now). Here is my rc.local btw:

=====================

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# enable autosuspend 
for i in /sys/bus/usb/devices/*/power/autosuspend; do echo 1 > $i; done
for i in /sys/bus/usb/devices/*/power/control; do echo auto > $i; done

# increase the emergency pool
echo 16384 > /proc/sys/vm/min_free_kbytes

# upclock the cpu on io
{
    sleep 90
    echo 1 > /sys/devices/system/cpu/cpufreq/ondemand/io_is_busy
} &

exit 0
