Morning,
stack_size = 0x4000 and seems to work fine.
Sorry, I didn't explain myself, changing CONFIG_LOGICAL_CPUS to 0 made
the compile process fail in northbridge.c so I had to change it back.
Yes disabling devices didn't make any difference so I leave them enabled.
hmmmm what else could I do??
THX,
Knut Kujat.
