Subject: Re: Dracut help
Round 2 . . .

So in my quest for diskless workstation, I found that if I boot more
than 6 at a time, after 10 minutes uptime, they freeze. Nothing in
/var/log/messages; nothing in the screen. And it's not a full lock - I
can switch from TTY to TTY, but "He's dead, Jim." I can do them in waves
of 6 with 2 minutes in between and that gets 24 up and running with no
problem.

Any ideas?

Regards,

George Toft
