Here is the dmesg. Hi, all I also encounterd the same problem and I think it's an severe issue for the arm arch. The issue only exists when building the kernel with gcc 4.8.x and CONFIG_FRAME_POINTER=y There was also a mail to describe the similar issue: https://lkml.org/lkml/2013/6/13/529 http://www.spinics.net/lists/linux-ext4/msg38685.html It can be easyly triggered when doing some ext3/ext4 operation and I got the following backtrace: ------------[ cut here ]------------ kernel BUG at linux/fs/buffer.c:2958!
