Re: A few questions about lenny on Qube2
Hi chaps,
A little update. My configure script has finished and both shells came back.
I can run commands like "ps ax" but "top" doesn't do anything. I attach to the top process with strace and it shows:
deb:~# strace -p 7228
Process 7228 attached - interrupt to quit
_newselect(0, NULL, NULL, NULL, {0, 500013}
Nothing else .... happens here
