Your post seems more informed than mine though
Interestingly, and I mentioned this in some other thread, I think that even in units not affected by the "normal" WSOD syndrome, certain (race?) conditions can occur to trigger the WSOD. A case in point may be connecting the tablet to a Linux OS (Ubuntu) running on vmWare Workstation 5.x in Windows XP and using Flasher, which causes XP to crash irrecoverably, and might cause some garbage to be sent over USB, which might confuse the LCD controller. All hypothetical of course, but I do have some strong circumstantial evidence I have rebooted my tablet 100+ times since getting it back from repair and the problem did not occur again. Legend has it that I should have experienced anothr WSOD in the first 10 or so reboots. This is all irrelevant to the current thread, of course, but I just thought I should mention it.
