Using 195.22 (also happens with 190.42), openSUSE 11.2 desktop kernel (188.8.131.52-0.1-desktop).
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)?
