They don't, unfortunately (nonetheless, they should be applied). The bug is 
still reproducible with this patch applied to the latest net-next version of 
sky2.[ch]. I am currently working on setting up a test environment to 
reproduce the bug and access the system console (serial line) as well as hard 
power reset. Both you and Mike (and David if it helps) will get the necessary 
access so that you can debug more efficiently on the system itself (without me 
being in the middle, slowing things down). I hope to have everything ready in 
an hour.

best regards,
Rene
