Other Parts Discussed in Thread: UKERNEL, TPS65218
Tool/software: Linux
Hi,
I am experiencing a crash when unloading the pvrsrvkm module (eg, when system poweroff is happening).
The graphics driver loads and works, I can run a Qt app using eglfs platform. (note crash occurs regardless of whether any app is run or not). When the module is unloaded it crashes and prevents the system from shutting down.
I am using the beagle bone kernel (Robert C Nelsons) based on 4.14.40 with a custom dtb file. The rootfs is built with yocto/poky, the powervr drivers come from the meta-ti layer (ti-sgx-ddk-km_1.14.3699939)
Following is the crash dump output, some info from dmesg and modinfo of the pvrsrvkm.ko
Has anyone has similar issue with 4.14?
does the crash dump give anyone a clue as to whats happening?
Cheers,
Marc
