There were a number of changes to change_page_attr for rhel4 u2 kernel. It be worth testing to see if it resovles your issue: http://people.redhat.com/~jbaron/rhel4/ any update on this? The problem still occurred with rhel4 u2 and vanilla 2.6.13.2 kernels. After much experimentation, I found that the crashes don't seem to happen (or are at least much less frequent) if the card doesn't probe my display device's specific EDID. I am not seeing the instability when I use the CustomEDID option of the nvidia driver (the same EDID it probes) while simultaneously using a video modem device that reports a different EDID and simply passes the video on to the device with the troublesome EDID. Very strange. In short, the instability does not appear to have anything to do with change_page_attr, but with the probing of the EDID. I do still see warnings from the nvidia driver when I use the rhel4 u2 kernel, but I haven't seen any instability so far. I still think that this should just work without me going through hoops, but I believe I'll have to work directly with nvidia (which I have been) to help them replicate this. This is nvidia's problem and not redhat's. Thanks for being interested, though. ok. closing then. please re-open if you think this is a Red Hat issue. thanks. |
