The bundled nvidia driver was upgraded from R173 (b99) to R177 (b100/101). Your boards were not included in moving the G3x GPUs to the R173 driver branch.
The error you are getting is an interrupt routing test failure. The driver plumbs the interrupt framework, purposely triggers an interrupt on the card and does a timed wait for delivery. One of the big changes in the Sun version of the R177 driver in b100/101 is using MSI interrupts by default if the card advertises them. The driver on the NVIDIA download page does *not* do this yet, so if this problem is masked by downloading their driver it points to a MSI delivery problem. In the Sun version of the R177 driver you can revert to using fixed interrupts by uncommenting the following line in /kernel/drv/nvidia.conf and rebooting: #Uncomment the following line if you need to disable the use of MSI interrupts #AllowMSI=0; Please try this to see if it masks the problem on your system. -- This message posted from opensolaris.org
