@arges - fyi the 20 nodes running
3.16.0-031600-generic #201408031935
have not encountered this problem in the ~2 weeks since install & reboot.
@matt-jarvis - thx for the verification, i was out-of-office most of
this week.
i just took the 20 nodes that had been running
3.13.0-38.65-generic #lp13
@matt-jarvis
Thanks for verifying this!

Title:
With the kernel 3.13.0-41-generic, I can confirm that we are now able to
run warm and cold resets of the mc via ipmitool correctly. On previous
kernel those commands would cause kipmi to use 100% cpu time and require
the ipmi modules to be unloaded and reloaded before ipmitool would
operate correct
The kernel 3.13.0-41-generic which is in proposed does not appear to
have any of the ipmi modules. Are we doing something wrong ?
root@adam:/lib/modules# uname -r
3.13.0-41-generic
root@adam:/lib/modules# modprobe ipmi_si
modprobe: FATAL: Module ipmi_si not found.
root@adam:/lib/modules# ipmito
Actually forget that, just worked out they are in the extras package

Matt - i am using the following (takes advantage of the ipmi_si module's hot
add and remove):
KIPMI_INST="0" # the web suggests this should increment but i've always seen 0
IPMI_PARAMS="$(cat /proc/ipmi/"${KIPMI_INST}"/params)"
sudo sh -c "echo "remove,${IPMI_PARAMS}" >

Looking through the code, I see the following commits:

that may be fixes to the issue.
Overall these are all in 3.16, and I'd like to see if this kernel is affected
by this
Matt - I've proposed a revert for the Trusty kernel:

Is there any news on this issue ? we have many nodes in our Openstack
cluster starting to suffer from this problem as we have a puppet fact
which runs ipmitool lan print and so triggers the bug often. Could you
also tell us what the workaround was for RHEL as we can't access the
page on RedHat's si
agreed. thank you for providing the test kernel!

Two weeks since comment #4 and no errors seems like pretty good evidence
that f60adf42ad55405d1b17e9e5c33fdb63f1eb8861 (ipmi: simplify locking)
is root cause.

the reboot was delayed but 7 of the 8 remaining hosts are now running the

this version.

I assume you performed the workaround suggested by Redhat on servers

the workaround red hat suggests (forcing a hot-add/hot-remove cycle of
the IPMI interface) appears to work. the same page claims the issue was
resolved w/kernel-2.6.32-504.el6 from Errata RHSA-2014-1392 (released
2014-10-14). however, i'm unable to pinpoint the resolution in the

i've installed and rebooted 16 of the 14.04 hosts so that they are now
running w/the 3.13.0-38.65-generic #lp1383921 kernel. i'll update the
ticket if i see the symptoms recur on this set.
the remaining 8 can't be rebooted until early next week.
