Korn's Jonathan Davis Wife's Death Ruled Accidental ... Fatal Drug Combo

Deven Davis -- wife of Korn singer Jonathan Davis -- died from the combined effects of 5 different types of drugs ... TMZ has learned.

According to new legal docs obtained by TMZ .... an autopsy revealed Deven had cocaine, heroin, clonazepam (a sedative used to treat seizures or anxiety), topiramate (nerve pain medication) and fluoxetine (used to treat depression) in her system when she died.

The docs say she was found dead in Bakersfield, California ... and her cause of death has been ruled accidental.

We broke the story ... Deven died in August around the same time Jonathan filed a request for a domestic violence restraining order against his estranged wife, claiming she had major drug issues. Deven had been living in a sober home, but went AWOL about a week before her death.

The Korn frontman later revealed she had been sick for nearly a decade ... and blamed mental illness and addiction for her death.

The 2 were married in 2004, but Jonathan filed for divorce from her in 2016. They had 2 sons together.

KoRn Ex Drummer Sues Band You Shucked Me!

David Silveria took a temporary break from drumming for KoRn -- and when he tried to rejoin the metal band, they turned him away ... so now he's suing.

According to the docs ... Silveria says his leave in 2006 was merely a hiatus, and he never gave up his ownership interest in KoRn. So, even though he wasn't jamming with 'em, he was still sharing the profits.

Silveria says when he was ready for his triumphant return in 2013, the other KoRn members -- Jonathan Davis, James Shaffer, Brian Welch, and Reggie Arvizu -- told him to kick rocks.

Silveria feels especially slighted because he claims Welch had taken a leave of absence, and was welcomed back with open arms.

Now, he's asking a judge to force the band to reveal how much cash they've made since he left -- so he can get his cut -- and then he wants to dissolve the partnership.

Korn Guitarist Hebrew Eyelid Tattoo ... On My Christian Face

Korn guitarist Brian "Head" Welch paid special tribute to the man upstairs -- BY TATTOOING A RELIGIOUS WORD IN HEBREW ON HIS FREAKING EYELID!!!

For you non-Jews (or you Jews that can't read Hebrew) the tattoo says, "Shekhinah" -- which essentially translates to mean God's presence on Earth.

... at least, that's what we think it means (sorry, it's Friday so our rabbis aren't picking up their phones).

Head -- who's a well known follower of the Christian faith -- posted the pic online today ... and apologized to his parents for getting such an extreme tattoo.

Head joins Hollywood's elite celebrity face-tattoo club -- alongside people like Mike Tyson, Gucci Mane, Lil Wayne and the Game.

Amen.

Metal Rockers Korn GROWING CORN While Recording Album

Korn has been hard at work the past few months using their indoor hydroponics setup to grow a few pounds ... of CORN!!!

Turns out the guys got real health conscious while recording their new album "The Paradigm Shift" -- and bought a micro-indoor farm to grow corn and other vegetables inside of the studio so they wouldn't have to buy from a store (photo below).

"TPS" will be a historic album when it's released in October since it marks the return of co-founding guitar player Brian "Head" Welch ... who left the band in 2005 for religious reasons.

Thankfully Limp Bizkit hasn't lived up to their name yet.
