While fuzzing 5.15.y kernel with Syzkaller, we noticed a INFO: task hung bug in fb_deferred_io_work()Which framebuffer device are you using exactly? It is possible that the problem is with the device driver, not core framebuffer.
I am not very sure about the answer, but the C reproducer uses(/dev/fb0)
int fd = open("/dev/fb0", O_RDWR, 0);
