[FGS] FGS and Linux 2.6 kernel

[Daniel Morissette]

I have noticed a similar issue recently and found that using packages 
from FGS 0.1 instead of the current 0.2 worked fine. I tried 
investigating and could not isolate the source of the problem.

We'd need Guillaume to confirm, but it is possible that the machine that 
he used for the 0.2 builds is different from the one used for the 0.1 
builds and that might be the source of the problem.
