Seems you filed this bugreport on the working amd64 system, not the arm 
one with the issue you are reporting.  That's not a problem in 
itself, but please do tell which exact kernel package you use.

Also, do you really use Debian, not Raspbian?  Subject mentions armhf 
but TTBOMK RPi is ARMv6 so is incompatible with Debian armhf (which 
requires ARMv7).

I strongly urge you to mention explicitly if using a derived 
distribution when filing bugreports against Debian, to avoid wasting 
time seeking needles in wrong haystack!


Regards,

 - Jonas


P.S.

Expect others than me to chime in and actually squash this bug - I just 
noticed those architecture-related details.
