>Description:
      When trying out 6.0-CURRENT kernel, it can not boot and compiled with debug enabled it says:

Fatak trap 18: integer divide fault while in kernel mode
cpuid = 0; apic id = 0
instruction pointer	= 0x8:0xffffffff80223c2d
stack pointer		= 0x10:0xffffffff8c371a10
frame pointer		= 0x10:0xffffffff8c371a60
code segment		= base 0x0, limit 0xfffff, type 0x1b
			= DPL 0, pres 1, long 1, def32 0, gran 1
procesor eflags		= interrupt enabled, resume, IOPL = 0
current process		= 28 (swi4: clock sio)
[thread pid 28 tid 100014 ]
Stopped at	ata_generic_command+0x5fd:	divq	%r14,%eax



My hardware is amd64 3000+ MSI nforce3 neo2 with 80GB WD hard disk. Please tell me if I should do anything else to provide you with more information
>How-To-Repeat:
      Compile kernel and boot. I've tried GENERIC and MYCONF with and without MODULES_OVERRIDE.
