[horirevens]

Hi guys, i need help about this error.

i have install Remastersys in my notebook and i have a custom-dist.iso from my Linux Mint 13 Maya. i also have install Virtualbox, but when i want to make a virtual machine using my custom-dist.iso, i have get an error like this

[87.457478] piix4_smbus 0000:00:07.0: SMBus base address uninitilized - upgrade BIOS or user force_addr=0xaddr

.

i have tried this thing :
1. lsmod | grep i2c_piix4
2. sudo nano /etc/modprobe.d/blacklist.conf
3. update-initramfs -u -k all
no error or warning like

Warning: No support for locale: en_US.utf8

in terminal any more when i set this. but why the message error

[87.457478] piix4_smbus 0000:00:07.0: SMBus base address uninitilized - upgrade BIOS or user force_addr=0xaddr
