Hi all.
We have a DM8148 custom board. We currently have kernel panics when loading vpss. The thing is that the panics and fails have a different behavior each time. But it still not possible to get to a working shell because of it.
The bootargs are
notifyk.vpssm3_sva=0xbf900000 ti814xfb.vram=0:24M,1:16M,2:6M mem=238M@0x80000000 vmalloc=486M vram=50M irqpoll 5
The kernel is compiled from latest PSP with Syslink built-in, and kernel notify. Project compiled with USE_SYSLINK_NOTIFY=0.
Here is some of the logs:
