ah, that's _another_ -tip testbox that broke at the same time, with a 
different kernel image. The RIP that corresponds to this box is 
0xffffffff80420470:

ffffffff8042045b <strnlen>:
ffffffff8042045b:       55                      push   %rbp

ffffffff80420470:       80 38 00                cmpb   $0x0,(%rax)


which could be consistent with the printk messup ...

i've double checked that 06e44f6af324 is applied. I'll bisect this.
