Default Strange microSD card + Safe Mode issue

I got 2 strange behavior with my tf701, running last tock firmware.

1. From time to time, when my tablet sleep, i got the message that my microsdxc card was mounted when i wake it up. If i look at my uptime, i got about 2 weeks of uptime so the tablet didn't reboot. Also the time at the mount point In Removable/microsd, the dateis the same as my last boot time. Got the same issue with another sd card, and also on my other tf701.

2. I just waking up my tablet from sleep, got no widget loaded as they are third party, and the safe mode indicator in the bottom left. I've took a look at my uptime, magically, 2 weeks ago. Also i got the message that my sdcard was mounted... About 6 hour ago, i was not in safe mode. Everything fine after a reboot, and my uptime reset to 00:00.

Any advice?
