So as I mentioned it to Dave Hansen already yesterday, I think the 
right, easily backportable fix would be to switch the kernel to 
'standard format'. It's very close to the compacted format and its 
behavior is much more obvious and it doesn't change the context size 
on us.

Then, on top of a known working kernel, we can re-introduce compacted 
format without pressure, with all the necessary signal frame 
conversion problems solved properly.

Thanks,
