[Xoom Q&A, Help & Troubleshooting] penarthpc:
I have a XOOM Wifi only MZ604 out of warranty.

Device randomly reboots on all variations of stock firmware, rooted/ unrooted, locked/ unlocked, custom ROMs tried, underclocking and lower settings tried. Device is completely dead and useless like this (rebooting randomly at all times). Have performed complete wipes, clears of caches, reinstalls of firwmare 20x and have easily spent over 12 hours with this awful device.

Below is my kernel panic dump, Im praying someone can offer some help on the matter. I've read many MANY horror stories about the same issue, and spoken with many who have written off their devices.
