[Nouveau] v4.8-rc2 crashes while probing nvidia graphics card on arm64
Hi, While trying out v4.8-rc2 on Juno r2 (arm64), I ran into the following crash when probing the nvidia graphics card attached to the PCIe slot. So I tried rc1 and got the same crash. The card probes without any errors on v4.7. Anybody familiear with the recent changes knows what might have led to the below crashlog?
