the x86.git qa mix produced this spontaneous reboot failure:

[   18.387888] Calling initcall 0xC0135EA8: test_sleep+0x0/0x1c()
[   18.394189] Auto sleep: Now 1201724894
[   18.395892] BUG: unable to handle kernel NULL pointer dereference at 00000160

[   18.411891] *pde = 00000000
 [ spontaneous reboot ]

config attached. Do you need any more info than this? Should i try to
