Hey, A few days ago I followed the page on 3ds.guide for upgrading to B9S (think I also updated luma at the same time) and when I was done with that I finally upgraded to the latest firmware version from 10.2 Since then I've experienced a few system crashes, most or all occurred while using homebrew apps. Basically I get kicked to a black screen, the last time the message said something about an error with arm11 core 0 and that it saved a file somewhere with a report of the crash, it then powers the system down. Sorry I cant be more specific; since I can't replicate a crash I don't remember everything that was in the error message or can even be sure if the message was the same every instance (occued maybe 3 or 4 times since going through with the aforementioned upgrades a few days ago). Basically trying to figure out if there's something wrong with my set up or if this has been happening to other people too. BTW problem is on a new 3ds if it matters. Thanks.
