Hello everybody,
Since kernel 3.18, I encounter a kernel crash each time when I copy a
big file (around 12 Gb) from an external USB drive to the harddrive of
my laptop.
I tried a bisection between kernels 3.17 and 3.18 and I was surprised to
find that this has to do with the driver of the wireless card
(rtl8188ee). However, I don't have problems if I copy the file while the
rtl8188 module is not loaded. Unfortunately, the results of git-bisect
are not totally conclusive because the kernel crash during boot when the
wireless connection is established. Here are the last steps of the
bisection:

Can somebody explain what's happening ? I do the copy via Dolphin in KDE
and the screen becomes black and the computer becomes totally
unresponsive. So, I don't have access to the logs to see the trace of
the problem.
Thanks in advance for your help,
François Valenduc
