Got the same, and if yes, then it definitily seems to be an effect of the problem with in-kernel(?) dcache corruption - the one which also results in BUGs at 000000000000000e, assertion "nikita-2050" in jnode.c and so on... BTW (@Edward): none of the problems can be reproduced on my VM with exactly same software configuration (copied root partition)...
