Default Re: 195.36.15 weird MSI behaviour

You can list all devices on your system with MSI capability:
(execute this command as root or use sudo in ubuntu like systems):
Code:
lspci -vvv | grep 'Message Signalled Interrupts'
The result will be like this:
Code:
        Capabilities: [b0] Message Signalled Interrupts: Mask- 64bit+ Queue=0/3 Enable+
        Capabilities: [50] Message Signalled Interrupts: Mask- 64bit+ Queue=0/1 Enable+
        Capabilities: [50] Message Signalled Interrupts: Mask- 64bit+ Queue=0/1 Enable+
        Capabilities: [50] Message Signalled Interrupts: Mask- 64bit+ Queue=0/1 Enable+
        Capabilities: [68] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable-
Enable+ means MSI is enabled and in use
Enable- means MSI is disabled and can be enabled (if driver supports MSI) in options.conf for example.

As you see I use MSI for everything except Geforce 8200.
