Interesting to see this post
I have a Viliv X70 UMPC and the only problem i have with it are these random lock ups which really pissed me off because I still cant figure out why (nothing helpful in event viewer, all drivers
are up to date).
I do however suspect that the USB controller could be a culprit because the lock up seems less frequent when I disable the "USB selective suspend" setting. Note I say less frequent, but still not completely cured. In my case the lock up happens not immediately on insertion, but randomly later.
Like I said, I suspect that it could be related to USB controller on my unit because again, if I don't insert any usb device, the lock up appears much less frequent.
Unfortunately on my UMPC, trying to completely not ever have to use any usb device is nearly impossible ;(. The wireless NIC is SDIO with the SD controller being linked to USB controller. Bluetooth is also USB related.
