now.. thing is, can anyone tell me what has happened at the end of this
transcript?? that last [|nfs] message from the gcx, is that incomplete??
or just an ack?? all that happens on the serial console now is a whole
lot of garbage.. i think its caused from some exceptions while handling
the irqs.
does anyone know of a description of how nfs works?? is it supposed to
load entire files into memory, or just the pieces of code it needs??
from the transcript, it looks like the kernel doesnt like my glibc very
much :)
any input would be well received..
