U530 dmesg error "ideapad_laptop: Unknown event: 1"

MikeW · 2014-11-20 06:26:43

I have Arch running on a Lenovo U530 I haven't really noticed any real problems. I am currious what this message in the dmesg output is though. The only thing that I don't have working yet is the webcam, everything else is functional including synaptic pad, and touch screen.

[ 628.064939] ideapad_laptop: Unknown event: 1
[ 649.256387] ideapad_laptop: Unknown event: 1

Some searching found that this may be related to wireless disconnect, but is not the case I haven't had any problems with wireless that I am aware of anyways.

Does anyone else have arch running on a similar machine and has some clue to what this message is all about?

What is your Wifi card?
What's its driver?

lspci | grep Net

Is there any help here ?

I don't think its the wfi causing it thats just what seemed to be showing up in google searches. In my case I haven't been having problems with wifi. It also starts with the message right after boot after wfi seems to be all setup and running ok. I will have a look over that link once I get home from work, thanks for that. The hard ware looks quite similar so maybe there is something there.

This is interesting too, looks like this is the code responsible. There may be some clues in there not that I understand all the code but the output lines may give me something else to look for in the logs.

Please get me this

$ /proc/config.gz |grep -i ideapad_laptop
$ lsmod |grep ideapad
$ find /usr/lib/modules -iname '*ideapad*'

I'd like to know if there's a module that's named ideapad_laptop and what is doing.
More infos are on its site

I'd like to know that too... I'll get you the info requested a little later tonight once I get done with this working for a living nonsense.

This may have something to do with airplane mode, which I don't care about to be honest.

Problem solved!

I noticed the message "Your Bios is broken; DMAR reported at address 0!", and went searching for updates just in case Lenovo fixed something. There was an update but the only fix listed was about the bluetooth setting not being able to be disabled.

I updated anyways even though my issue was not listed. Guess what its fixed, the system boots clean now.

Just incase anyone else runs into this issue, the bios update that fixed my U530 machine was 7ccn61ww.

Update: I spoke too soon, its not solved but not happening near as often so it looked solved. It took quite a while to show up this time. This may be related by it started up in the log after the monitor as blanked and then reactived. The flash update did solved a few other problems though.

Update2: Now I see why I didn't notice it after flashing bios. This seems to be tied to power management. When on AC the Unknown event spam stops. When on battery that message shows up about every 20 seconds.

one more step forward
You may see if there're some parameters to pass to the module

$ modinfo ideapad-laptop |grep parm
parm:           no_bt_rfkill:No rfkill for bluetooth. (bool)

So you may add to your kernel command line something like ideapad-laptop.no_bt_rfkill=0.
For testing it isn't needed permanent, so you should use the edit feature of your boot loader while booting and add the command there. E.g. for grub and gummiboot just press key e while is booting, before timeout, and modify the kernel line.
If that won't do anything, file a bug report to the developer site. I think he will be interested to pose a fix.

Adding the boot parameters did not appear to do anything. Going to head upstream to see if I can find an existing bug or report a new one myself.

Yeah, you have the right to do that. My suggestion : put +"ideapad-laptop" +network host:lkml.org in you search engine
