Hi all, I've been experimenting with the Nouveau driver on Tegra for a few days now and made some promising progress. The one thing that keeps throwing me back is that I get seemingly random system lockups, which are not recoverable. I think this could be the same issue that was reported by Jay Agarwal earlier. (Message-id: <C79B248886DD134989C8FF6B096A91AB91B603D82B@xxxxxxxxxxxxxxxxxxx>) I also found a WAR for a system hang issue in the NVidia downstream kernel [1], but when tried on upstream it had no effect on the issue. I'm reasonably sure that this is not driver software related, as I've already hunted down most of the caching issues and acceleration seems to work at this point. So either this is a random HW hang, or there is some software condition I'm not aware of. I'm running a NV92 connected to the NVidia Beaver board. Kernel is next-20130809 with the PCIe series + the LP2 workaround applied. Could you please investigate if there are any other known errata for the Tegra PCIe controller, which could hang the entire system?
