Hmm, I still have 2.4.16-pa4 here and it definately shows 
"2.4.16-pa4" for me. Maybe a SMP problem ?
You could try to double the size of the udelay() parameter
in lcd_print to see if it cures your problem.

Currently I use "kill_proc(1, SIGINT, 0);" to kill the init-process -
which is normally a reboot-command and gives the above messages.
That's AFAICS not the right solution, but nfortunately I don't know
how to do it correct right now.
The other thing is, that this call will not work if the init-process
doesn't has PID 1 - this happened to me after a kernel crash, where
init needed to fsck.
