I also started seeing this stuff sometime this weekend.  My symptom is
tar complaing about a corrupted file when untaring something large (say
11MB).  Unmount/Remount the fs, and the tar extracts just fine.
I was going to play around with my RAM to see if it was the culpret, but
this second report makes it look like a software bug.
