Yes I did. I got it two days in a row. It turns out that it was DMA disk errors.
The kernel then remount the disk read only.

Use smartmontools to check your disk status:

sudo /usr/sbin/smartctl -a /dev/hdx

There must be some errors logged. 

The cause? Who knows ....
Power supply, old disk, bad stabilizer, bad luck, etc ....
