I have a new nexus 7 32gb tablet all stock v4.2.1 and have been getting these random reboots too. I don't think it is caused by the chrome browser because I got the reboot while using firefox beta too. All debug error logs I've seen show that the FATAL EXCEPTION is triggered by a java null pointer or null value exception in the a xroid.os.parcel method. And/or an illegal argument passed in to the method which is probably a result of the bad null value pointer. I also have seen reports of this reboot issue from half a year ago on nexus devices. So it disturbs and concerns me that Google refuses to treat this as a high priority problem to fix. It leads me to believe that they can't figure it out after all this time. Maybe they need to hire more talent. It just doesn't make sense that they would ignore it for this long and not rate it as a very high priority.
hmmm... very interesting. under what conditions is this method called?
I can cause a reboot 100% of the time under following conditions:
- Using Android Transfer Utility to transfer multiple files (say more than 20) or any 'large' (> 250MB) file. I have a Macbook Pro.
- using tTorrent to download anything - uTorrent does not cause crashes (but is way suckier than tTorrent!)
in addition, pretty much ANY heavily processor intensive activity - or perhaps R/W activity? - will have at least a 50% chance of causing a reboot.
