Title:
  makedumpfile --dump-dmesg fails on 3.5 kernels and later

Status in “makedumpfile” package in Ubuntu:
  Fix Released

Bug description:
  When used on Ubuntu running kernel 3.5 and later (Quantal, raring and
  Precise 12.04.02) the makedumpfile --dump-dmesg /proc/vmcore
  /tmp/dmesg fails with the following error :

  # makedumpfile --dump-dmesg /proc/vmcore /tmp/dmesg
  dump_dmesg: Can't find some symbols for log_buf.

  makedumpfile Failed.

  This is caused by the change from byte-buffer structure to
  variable-length record buffer of the kernel log buffer introduced by
  this commit :
  	http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=7ff9554bb578ba02166071d2d487b7fc7d860d62

  The same issue occurs on Debian and is identified in Debian bug
  #698755 :
