In this particular case, there were two ext4-related crashes as well: https://syzkaller.appspot.com/text?tag=CrashReport&x=14c7dd1b480000 https://syzkaller.appspot.com/text?tag=CrashReport&x=1153a07f480000 I think syzbot picked a too generic frame as a bug title and it just got confused by crashes belonging to different filesystems. Maybe we need to display subsystems for individual crashes as well, so that it's easier for a human to understand what's going on.. -- Aleksandr > > - Ted > > -- > You received this message because you are subscribed to the Google Groups "syzkaller-bugs" group. > To unsubscribe from this group and stop receiving emails from it, send an email to syzkaller-bugs+unsubscribe@xxxxxxxxxxxxxxxx. > To view this discussion on the web visit https://groups.google.com/d/msgid/syzkaller-bugs/ZE4NVo6rTOeGQdK%2B%40mit.edu.
