In order to answer your queston (Load_Cycle_Count variations as seen by 
smartctl under B2 )
I decided to recompile the kernel as that is a fairly heavy loadwork.

Here are my observations
# last night when I noticed your email
linux:~ # smartctl -a /dev/sda  | grep Load_Cycle_Count
193 Load_Cycle_Count        0x0012   100   100   000    Old_age   Always       
-       2729


# today before compiling kernel
linux:~ # smartctl -a /dev/sda  | grep Load_Cycle_Count
193 Load_Cycle_Count        0x0012   100   100   000    Old_age   Always       
-       2730


# today after compiling kernel
linux:~ # smartctl -a /dev/sda  | grep Load_Cycle_Count
193 Load_Cycle_Count        0x0012   100   100   000    Old_age   Always       
-       2734


# today after booting using the new compiled kernel 
linux:~ # smartctl -a /dev/sda  | grep Load_Cycle_Count
193 Load_Cycle_Count        0x0012   100   100   000    Old_age   Always       
-       2737


Wifi works fine under the new kernel but my usb hotplug doesn't work now (I'm 
using
new compiled kernel) - what do I need to do to get it working again?


Regards
James
