1. After booting 2.1.93, I started composing this letter
and editting a file under X windows ( + Xemacs and a couple of
xterm's), and, in the midst of that, my machine locked up hard.
2. printk's seem very slow. There seems to be a pause
every time a new line is printed. The result is somelike
like a 2400 baud console, although the pauses are between
lines rather than between characters.
3. printk's executed earlier in the kernel are apparently
not being exeucted (e.g., "printk(linux_banner);" in
linux/init/main.c). Maybe their executing is being
deferred? I did not check the one time when I did boot
2.1.93.
Anyhow, I hope this information is helpful in developing the
correct fix.
