realtek: No valid SSID, checking pincfg
### FIXED (overriding)
## https://bugzilla.redhat.com/show_bug.cgi?id=785417
## http://comments.gmane.org/gmane.linux.kernel/1011314
# Driver requires SSID but vendor do not provide it (not following policy).
# Already patched on upstream kernel. SSID injection as follows:
realtek: Enabling init ASM_ID=0x862d CODEC_ID=10ec0269

ath3k: probe of 3-4:1.0 failed with error -110

vboxdrv: module verification failed: signature and/or  required key missing - tainting kernel
### FIXED (ignore it!)
## The module verification warning is unrelated, it means that the kernel you use (Ubuntu?) has
## module verification enabled and that the key was not available when building (obviously, the
## keys must be kept secret or it would be rather useless to have module signing).

### FIXED (follow Implementation police instead ACPI police)
## https://github.com/Bumblebee-Project/bbswitch/commit/ee0591b
# The ACPI Warning here is harmless (though it can be annoying because it gets repeatedly printed during toggles)
# /* Although the ACPI spec defines Arg3 as a Package, in practise
#  * implementations expect a Buffer (CreateWordField and Index functions are
#  * applied to it). */
#  params[3].type = ACPI_TYPE_BUFFER;
