--- Comment From gpicc...@br.ibm.com 2015-12-07 21:56 EDT--- Quick update/information: I wasn't able to perform DLPAR in the way described on bug. Normally I use command-line tool called "drmgr", and even with this tool, I couldn't perform DLPAR in the usual way. I was able to add the adapter in LPAR via HMC, with partition powered off. Then, once it boots, I was able to see adapter there, and in this scenario I could perform DLPAR using the "drmgr" tool without issues, i.e., bug wasn't reproduced in this case. The problem is that, if the adapter is not present as "required" in LPAR configuration, i.e, if the adapter is not present on partition boot time, the DLPAR facility does not work for me. I got messages like -"Dynamic reconfiguration is not supported for connector type slots on this system" ; -"Validating PHB DLPAR capability...yes. There are no DR capable slots on this system. Could not find drc index for 32, unable to add thePHB." in partition console (when using "drmgr" command) or the message "RMC network connection to the source partition is not present" in HMC, when trying DLPAR via web interface. Sachin, do you know what's going on? Can you help me perform the correct DLPAR operation to reproduce the bug? BTW, Murilo (my co-worker) suggested that the machine's firmware level is too outdated - should we upgrade it?

[Kernel-packages] [Bug 1486180] Comment bridged from LTC Bugzilla
--- Comment From cha...@us.ibm.com 2016-01-11 10:34 EDT---
Status update:
The root cause was found, and a patch is provided.
The problem happens when DLPAR of PCI device is done in LPAR with no PCI
devices present at boot time. When DDW is being enabled (in function
query_ddw() specifically), a NULL pointer dereference happens because a member
of struct eeh_dev is NULL.
This is caused because EEH is not initialized correctly, by not probing
PCI devices as expected, and so not initializing the eeh_dev struct.
The commit 89a51df5ab1d ("powerpc/eeh: Fix crash in
eeh_add_device_early() on Cell") added a check to avoid oops in Cell
architecture in function eeh_add_device_early() - this function is used
to probe PCI devices in hotplug/DLPAR operation. The check is performed
by evaluating the return of eeh_enable() function.
The issue then happens because since we have no PCI device on boot time,
EEH is not enabled and this check fails on eeh_add_device_early(). Our
patch changes the way the arch checking is done, and so this bug does
not happen anymore.
The patch was submitted upstream. I don't know exactly the procedure regarding
Canonical - I think we should wait the upstream acceptance and then request
Canonical to add the patch to Ubuntu's 14.04.4/15.10/16.04 kernel.
The patch's description provides a bit more details of the issue and the
proposed solution.

Thanks Shryia for all the help provided.
Cheers,
Guilherme

Title:
Kernel OOPS during DLPAR operation with Fibre Channel adapter
Status in linux package in Ubuntu:
New
Bug description:
-- Problem Description --
Kernel OOPS during DLPAR operation with Fibre Channel adapter
---uname output---
4.1.0-1-generic
---Additional Hardware Info---
Fibre Channel: Emulex Corporation Saturn-X: LightPulse Fibre Channel Host
Adapter (rev 03)
Machine Type = POWER8
---Steps to Reproduce---
1) Install Ubuntu 15.10 on a Power VM LPAR.
2) Configure and start rtas_errd daemon
3) Via HMC try to add a Fibre channel adapter via dynamic partitioning
During the operation following OOPS message is observed
