I updated from 12.04 to 12.10 (AMD 64bit) last night and have been having this exact same problem. I have a fairly new WD 750Gig black HD with / and /home partitions. Through-out the day, either / or /home has been suddenly going into read-only mode and all I can do is reboot to get it back to normal.
