The output of lspci -vvv
I have an annoying ACPI-Bug. On every boot I get the following Warning/Error message:
[ 0.459917] [Firmware Bug]: PCI: MMCONFIG at [mem 0xe0000000 - 0xefffffff] not reserved in ACPI motherboard resources
Then the notebook boots just fine.
But I think, there are some other problems related to this <Warning/Error>.
When I run the notebook on battery and plug in the AC, the performance becomes very bad until I suspend/reactivate the notebook or plug out the AC again.
There is nothing logged about this, no visible problems like busy CPU or full RAM, the notebook just becomes very slow so that I cannot work with it anymore.
This sometimes also happens, when I boot with AC plugged in. I don't know how to describe the problem more detailed. I added the output of lspci -vvv, dmesg and lshw as attachment.
Some information from BIOS Setup Menu:
Bios-Version: 1.11 (8GET34WW)
Embedded Controller Version: 1.06
Machine Type Model: 7826W12
If you have any ideas or need more information, please tell me.

The output of dmesg
Can you provide the output of the following:
Additionally, your dmesg shows that you have the vbox modules loaded and in use. Particularly the line:
[ 637.727743] EXT4-fs (dm-2): Unaligned AIO/DIO on inode 10486440 by VirtualBox; performance will be poor.
While that seems unrelated, it can certainly impact performance. For the purposes of debug, do you see the performance issues when the vbox modules are not loaded and vbox isn't in use?

Yes, of course. I added all those information as attachments. The machine is running good at the moment. I will also add them, when the problem appears again (Hopefully today). You must know, it is not that easy to reproduce. To let it happen with a high chance, the battery must me quite empty, laptop must have been in standby and I must plug in the AC. Or something weird like that.
After that, I will look, how to disable the vbox-modules at boot and disable them (Can you tell me, how this is done in an easy way, I don't often work on things like that).

slow system: acpidump
Ok. It happened again right now.
My battery was on ~40% capacity, I plugged in the AC and booted the laptop. The performance was bad. That means, it boots slower, gdm needs about 30-40 seconds to come up and even a login on tty2 needs seconds to work. I then collected the information (acpidump and the /sys-things (see attachments)), suspended the system and woke it up. Now, everything is fine. I did not deactivate the vbox-module yet.

Is this still happening with 2.6.43/3.3? Does it happen without the vbox modules loaded?
