I've put old code in current Curent and get same panic.
I've need a gun but I do not know the object of it application
this one PC or me self. I need to check sources one more
time. I've really tired of it.


By the way, in any case ACPI this problem or not (in case
I've mixed up sources) could you point to any "ACPI for
dummies" resource so that I will be able to understand smth
from ACPI code?
