NVRM: failed to enable MSI
1 Attachment(s)
Using 195.22 (also happens with 190.42), openSUSE 11.2 desktop kernel (
I appended "NVreg_EnableMSI=1" to one of the files in "/etc/modrpobe.d" which already contains "options nvidia NVreg_DeviceFileUID=0 NVreg_DeviceFileGID=33 NVreg_DeviceFileMode=0660".

The following warning appears in dmesg:

NVRM: failed to enable MSI,
using PCI-E virtual-wire interrupts!

Is this expected behavior?
Maybe MSI feature is disabled in these drivers (like UseEvents)?

[    0.365815] pci 0000:00:00.0: MSI quirk detected; MSI disabled
The kernel is disabling MSI for your hardware because it is known not to work on it.

Re: NVRM: failed to enable MSI
Specifically, MSI is disabled on your particular VIA chipset since it's believed not to work properly on it.

Re: NVRM: failed to enable MSI
You probably do not loose anything by not enabling MSI on your Geforce 8400m. I have Geforce 8200 and enabling MSI causes serious hangs and thanks to this errors on disk because of not clean system shutdown. However there are 2 reports that MSI works perfect on quadro nvs140m and GTX 285:
So MSI only works well with few GPUs.

Re: NVRM: failed to enable MSI
Well, I remember having MSI successfully enabled in the past, but the recent experiment caused me a lot of troubles (e.g. could not play large videos).

Anyway, I don't know if this is related, but my graphics card permanently broke :(:mad:.
I'm seeing these symptoms again: http://www.nvnews.net/vbulletin/showthread.php?t=130082
This time, however, the laptop is out of warranty. The repair would cost half of the laptop's initial price.
Seems that every year my laptop's graphic card breaks :(.
