Kernel Panic near inphy0

[Remi L.]

I am currently trying to upgrade from 5.1-RELEASE to current on my Sony VAIO
laptop, model number GRX-570. On first boot of CURRENT kernel a panic occurs
right after inphy:

Fatal trap 12: page fault while in kernel mode
Fault virtual address=		0xdeadc0de
Fault code=				supervisor write, page not present
Instruction pointer=		0x8:0xc0
Stack pointer=			0x10:0xc077e7b8

Current process=          	0 (swapper)
Kernel type 12 trap, code = 	0

Is there a fix or workaround currently for this error?
