Title:
  rcu_sched_state detected stalls on CPUs/tasks: { 20} (detected by 38,
  t=xxxxxx jiffiles)

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  The message above was repeated, with changes in the CPUs and the
  number of files; end result was system either did not boot (more
  probable, nothing visible in the syslog after a successful reboot), or
  completely failed soon after boot.

  Sequence (times in UTC):

  * on 21012-02-22 17:55 the system was dist-upgraded (see below for
  packages upgraded), but not rebooted.

  * at around 19:09, same day, system became unresponsive. Due to a
  series of other issues, access to the console (via KVM, system is on a
  remote, lights-off, site) was not possible;

  * at least twice until 02:00 2012-02-23 system was rebooted via the
  power control interface, still failing to appear available under SSH;

  * at around 02:00 remote KVM access was successful, and the message in
  the bug title was collected;

  * another reboot was attempted, now successful.

  A brief search on Google shows many hits for this message. It is
  unknown if the dist-upgrade has any causal relation to the error.
