Subject: Re: commit c2fe0480cd77 leads to hang on boot

Message-ID: <20240829230438.3226-1-spasswolf@web.de> (raw)

To look into the issue I applied the following patch to next-20240829:
diff --git a/drivers/video/fbdev/efifb.c b/drivers/video/fbdev/efifb.c
index 20517448487e..ba2b0d4b1bd3 100644
--- a/drivers/video/fbdev/efifb.c
+++ b/drivers/video/fbdev/efifb.c
@@ -573,6 +573,8 @@ static int efifb_probe(struct platform_device *dev)
pr_err("efifb: cannot acquire aperture\n");
goto err_fb_dealloc_cmap;
}
+ printk(KERN_INFO "%s: not calling devm_register_framebuffer\n", __func__);
+ goto err_fb_dealloc_cmap;
err = devm_register_framebuffer(&dev->dev, info);
if (err < 0) {
pr_err("efifb: cannot register framebuffer\n");
Now booting works again so the problem seems to be in devm_register_framebuffer().
