Unsupported PM cap regs version (7)

Postby mikesol on Sat Jun 27, 2009 3:59 pm

Hello guys,

I have a little issue with Gloria, when I start my laptop appears this message

Unsupported PM cap regs version (7)

And stay there about 30 seconds, after that all run normally.

Is there any problem with my hardware?

I'm using a Toshiba Laptop A305.

Thanks in advance.

I found an explanation

Code: Select all
pm cap regs version (7)
power management capabilities register version 7

some pci device in your computer uses version 7 which apparently is not supported by the kernel as of yet.

You can use sudo lspci -v and look to see which pci device uses version 7.

In my case it was the LAN card. So I went into the BIOS and disabled it and did not get a message.
So there is no danger to your system. It just cannot fully manage all the power options available to one of your pci devices. Probably the NIC. Its just too bad I still have to see that dang message every time.


So i execute the lspci -v command and the device using version 7 is my Ethernet controller

Code: Select all
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 02)
   Subsystem: Toshiba America Info Systems Device ff1e

   Capabilities: [160] Device Serial Number 00-00-ff-ff-00-00-00-08
   Kernel driver in use: r8169
   Kernel modules: r8169


I don't know how to remove that message, because if I disable the ethernet in the bios, I won't have internet, right?. Any help is appreciated.

thanks
