Hello, Has anyone else seen symptoms similar to those described below? The RPI2 experiences odd panics displaying complaints like... <----------> panic: sleepq_add: td 0xc3a5e370 to sleep on wchan 0xc3afd000 with sleeping prohinited cpuid = 0 KBD: enter: panic [ thread pid 11 tid 100008 ] Stopped at $d.10: lrdb r15, [r15, r15, ror r15]! db> <-----------> It does not seem to matter anything whether the system is busy or relatively idle. What seems to be common to these panics is that in most cases when they happen the keyboard hasn't been touched for a while. This is just a wild guess, but maybe the kernel tries to put something in some low energy mode and fails. If I leave the thing doing something on its own for a while, when I get backsome 5 to 15 minutes later the poor RPI2 has fallen on its face showing the panic message similar to the one shown above. Have you seen this happening? Any ideas what might be going on? --jau
