Hello,

I was trying to find out why IPMI stopped working on new kernels. Since 2.6.39 module loading ends with following message:

ipmi_si: Interface detection failed

Then ipmitool is unable to control IPMI device.

Works for 2.6.38, doesn't work for 2.6.39, 3.0.28, 3.4-rc1.

I got this bisected to following commit:

commit a1e9c9dd3383e6a1a762464ad604b1081774dbda

ipmi: convert OF driver to platform driver

of_bus is deprecated in favor of the plain platform bus. This patch merges the ipmi OF driver with the existing platform driver.

CONFIG_PPC_OF occurrances are removed or replaced with CONFIG_OF.

Compile tested with and without CONFIG_OF. Tested OF probe and default probe cases.

I wonder whether this is a bug, or I'm doing something wrong?

Thanks in advance!

If it used to work and now it doesn't, that's probably a bug, though you might be able to work around it with some direct settings.

What hardware is involved? 'cat /proc/ipmi/0/params' on a working kernel would be handy. You can use that information to hot-add the BMC, that should be documented in Documentation/IPMI.txt

It has been working for me as a module in the DT case.

This driver has several init paths with acpi, pci, fixed standard addresses, and device tree. Can you provide some details on your h/w and kernel log of working the working case.

(not sure whether I got them correct though, and values mostly seem to me to be defaults anyways..)

Hello,
I was trying to find out why IPMI stopped working on new kernels. Since 2.6.39 module loading ends with following message:
ipmi_si: Interface detection failed
Then ipmitool is unable to control IPMI device.
Works for 2.6.38, doesn't work for 2.6.39, 3.0.28, 3.4-rc1.
I got this bisected to following commit:
commit a1e9c9dd3383e6a1a762464ad604b1081774dbda
Author: Rob Herring<[email protected]>
Date:   Wed Feb 23 15:37:59 2011 -0600
ipmi: convert OF driver to platform driver
of_bus is deprecated in favor of the plain platform bus. This patch merges the ipmi OF driver with the existing platform driver.
CONFIG_PPC_OF occurrances are removed or replaced with CONFIG_OF.
Compile tested with and without CONFIG_OF. Tested OF probe and default probe cases.

I wonder whether this is a bug, or I'm doing something wrong?
Thanks in advance!
with best regards

Hi Corey,

I have this problem with 3.4-rc4 as well and it already contains b1608d69cb804e414d0887140ba08a9398e4e638, so this doesn't fix this problem..

Hello,
I was trying to find out why IPMI stopped working on new kernels. Since 2.6.39 module loading ends with following message:
ipmi_si: Interface detection failed
Then ipmitool is unable to control IPMI device.
Works for 2.6.38, doesn't work for 2.6.39, 3.0.28, 3.4-rc1.
I got this bisected to following commit:

ipmi: convert OF driver to platform driver
of_bus is deprecated in favor of the plain platform bus. This patch merges the ipmi OF driver with the existing platform driver.
CONFIG_PPC_OF occurrances are removed or replaced with CONFIG_OF.
Compile tested with and without CONFIG_OF. Tested OF probe and default probe cases.

In the previous kernel it was coming up at address 0xca2, not 0xca8. Can you try that?

Hi Corey,
I have this problem with 3.4-rc4 as well and it already contains b1608d69cb804e414d0887140ba08a9398e4e638, so this doesn't fix this problem..
Can you send the kernel log for the failing case.

Hello,
I was trying to find out why IPMI stopped working on new kernels. Since 2.6.39 module loading ends with following message:
ipmi_si: Interface detection failed
Then ipmitool is unable to control IPMI device.
Works for 2.6.38, doesn't work for 2.6.39, 3.0.28, 3.4-rc1.
I got this bisected to following commit:

That means that something else is using that I/O space. You can look in /proc/ioports to find what.

nothing on this address (with 3.4 kernel).

on 2.6.32 I see:
0a30-0a3f : pnp 00:07
0b00-0b7f : pnp 00:0c
0ca2-0ca2 : ipmi_si

d000-d01f : 0000:06:00.0

on 3.4-rc4:
0a30-0a3f : pnp 00:07
0b00-0b7f : pnp 00:0c
0cf8-0cff : PCI conf1

  c000-cfff : PCI Bus 0000:06
    c000-c01f : 0000:06:00.0

I'll try comparing both kernels' dmesg output in more detail to see if there's some difference that might be important..

Hi Corey,
I have this problem with 3.4-rc4 as well and it already contains b1608d69cb804e414d0887140ba08a9398e4e638, so this doesn't fix this problem..
Can you send the kernel log for the failing case.

I do not know. I just tried 3.2 and the head of the kernel tree and they both worked fine on my system, which is an old Intel server.

I have a Supermicro system with IPMI, but it will take me a bit to get a working kernel there.

Could you try with the module param "kcs_debug=7"? That will give me some idea what the state machine is doing.

At this point, if I can't reproduce, I can't do much. I also don't see how that patch would make any difference if you hand-specify the parameters.

Hi Corey,
I have this problem with 3.4-rc4 as well and it already contains b1608d69cb804e414d0887140ba08a9398e4e638, so this doesn't fix this problem..
Can you send the kernel log for the failing case.

Hello,
I was trying to find out why IPMI stopped working on new kernels. Since 2.6.39 module loading ends with following message:
ipmi_si: Interface detection failed
Then ipmitool is unable to control IPMI device.
Works for 2.6.38, doesn't work for 2.6.39, 3.0.28, 3.4-rc1.
I got this bisected to following commit:

Re: [BISECTED] SOLVED ipmi_si not loading since 2.6.39

Hi guys,

thanks for all Your help. Problem solved, I have to be very sorry about that :( There was a boot script I wasn't aware of which we're using for setting IPMI and this tried to load the module using
modprobe ipmi_si type=kcs ports=0xca8 regspacings=4
THIS seems to have stopped working, but I think it was just wrong all the time, and is now not needed at all. Just loading ipmi_si now works, so the system was maybe just getting confused when trying to load module with wrong params (I was unloading module first, but seems like that wasn't enough).
So I'll just have this script fixed (or better removed).
I'm once again sorry for the fuss, I don't know much about how IPMI works and apparently haven't gathered all the needed info.

Cheers!

nik

Hi,

any idea anyone? Simply reverting this patch is not possible due to further modifications so I haven't tried this yet..

Any hint on what could I try? (specifying some module parameters, etc..)

Thanks!

Tried setting parameters by hand didn't help:

(not sure whether I got them correct though, and values mostly seem to me to be defaults anyways..)

Hello,
I was trying to find out why IPMI stopped working on new kernels. Since 2.6.39 module loading ends with following message:
ipmi_si: Interface detection failed
Then ipmitool is unable to control IPMI device.
Works for 2.6.38, doesn't work for 2.6.39, 3.0.28, 3.4-rc1.
I got this bisected to following commit:
commit a1e9c9dd3383e6a1a762464ad604b1081774dbda

ipmi: convert OF driver to platform driver
of_bus is deprecated in favor of the plain platform bus. This patch merges the ipmi OF driver with the existing platform driver.
CONFIG_PPC_OF occurrances are removed or replaced with CONFIG_OF.
Compile tested with and without CONFIG_OF. Tested OF probe and default probe cases.

I wonder whether this is a bug, or I'm doing something wrong?
Thanks in advance!
with best regards
