Hi, I have some random black screen with an exception error. Most of the time it's an ARM11 error with different running process, and once it was ARM9 error. Sometimes I can play with no error (for an hour for example) I checked my SD, it's fine (with h2testw). I have the last luma release but it happened with the one before too I'm on 220.127.116.11U I have a lot of dmp files if someone needs! Thank for your help.
