If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
focal to verification-done-focal. If it does not fix the bug for you,

not be able to proceed.

Title:
  makedumpfile does not create dmesg file in /var/crash on 5.10+ kernels

  Fix Released
Status in makedumpfile source package in Focal:
  Fix Committed
Status in makedumpfile source package in Hirsute:
  Fix Released
Status in makedumpfile package in Debian:

Bug description:
  [IMPACT]
  makedumpfile does not create the dmesg.<timestamp> in /var/crash.
  This happens only on 5.10+ kernel because 5.10 kernel introduces a new
  lockless ringbuffer.

  This issue has been addressed upstream with commits :
  [1] c617ec633392([PATCH 1/2] printk: add support for lockless ringbuffer)
  [2] 44b073b7ec46([PATCH 2/2] printk: use committed/finalized state values)

  [TEST CASE]

  For testing a machine running focal with the 5.11 kernel is required.
  Then trigger a crash.
  After reboot make sure that dmesg.<timestamp> file is created in /var/crash/<timestamp>

  [WHERE PROBLEMS COULD OCCUR]

  Any problems would involve the dmesg file not created.
