[Barrelfish-users] barrelfish help!

[Antonio Barbalace]

Dear all,

I am now trying to run the bomp experiments.

Just to make some context, I am using a tftp server. bomp_benchmark_ft is
loaded by the menu.lst/grub (maybe is not the right way to do it). I am
attaching menu.lst.

This is what happen when I am loading bomp_benchmark_ft (also without
arguments, the same errors are reported during boot):
