I'm having a little problem with ACPI I got this error at dmesg:
# dmesg |grep -i error [ 11.683927] ACPI Error: [\_SB_.PCI0.GFX0.DD02._BCL] Namespace lookup failure, AE_NOT_FOUND (20131218/psargs-359) [ 11.683931] ACPI Error: Method parse/execution failed [\_SB_.PCI0.RP05.PEGP.DD02._BCL] (Node ffff88022707b050), AE_NOT_FOUND (20131218/psparse-536)
And I don't really know if by it self is a problem. What a know is that from time to time I got a kernel panic, related to this.
So I've made some research and a lot of the topics I found tell me just: "don't worry... just reboot yout computer."
But that's not really a soluction, is it?
Anyone has had this problem? Any tips on how can I fix it?
