Title:
rcu_sched_state detected stalls on CPUs/tasks: { 20} (detected by 38,
t=xxxxxx jiffiles)
Status in linux package in Ubuntu:
Won't Fix
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.
