Installed them last night on my 8204 and whenever I unplugged the laptop instant BSOD then restrart. Wierd thing is the BSOD keeps appearing before I get to the login page in windows so the comp goes into a loop of restart, chkdsk, then BSOD, and so on. I finally fixed it by restarting with the last known good configuration and went back to 6.8 no problems.
Beware...
