@Rafael, seems that it's caused by:
commit ea9f8856bd6d4ed45885b06a338f7362cd6c60e5
Author: Igor Murzov <intergalactic.anonym...@gmail.com>
Date: Fri Mar 30 21:32:08 2012 +0400
ACPI video: Harden video bus adding.
It is always better to check return values, so add some new checks and
correct existing ones.
v2: Be consistent and don't mix errors from -E* and AE_* namespaces.

In particular:
@@ -1343,15 +1343,17 @@ static int
acpi_video_bus_get_devices(struct acpi_video_bus *video,
struct acpi_device *device)
{
- int status = 0;
+ int status;
struct acpi_device *dev;
- acpi_video_device_enumerate(video);
+ status = acpi_video_device_enumerate(video);
+ if (status)
+ return status;
And indeed, previously I got an ACPI exception and now I still do, but with
addition of the probe failure:
ACPI Exception: AE_NOT_FOUND, Evaluating _DOD (20120320/video-1147)
video: probe of LNXVIDEO:00 failed with error 5
So I think this is the expected behaviour?
