[net.unix-wizards] Bug in DH/DM driver or Automatic Reboot

sohail@terak.UUCP (04/10/84)

We had a problem with using DH/DM boards with our VAX 750 with 4.1BSD
("login" would hang after the user id had been typed in.)

This problems appear to be solved, since we got a new, 'FIXED',
DH/DM board from ABLE.

We now have another problem.


PROBLEM:

While booting up the system will auto-configure, but will
not enter the 'automatic reboot' sequence, until a character
is typed on the console.

Once the character is typed the message
	"automatic reboot in progress" 
is printed out and the system proceeds to boot.



MORE INFORMATION:

Configuration:	VAX 750, UDA 50, RA 81, TU 80, DMF-32, DH/DM

We did not have this problem when we had only the DMF-32 in the system.



QUESTIONS:

Is this a problem with the DH/DM driver.
			   DH/DM board
			   something else in the kernal.


We would appreciate hearing from any body who can shed light on the
subject.

Thanks in advance.

The auto-reboot bug is either in init or in the kernel.  This
problem has nothing to do with the DH/DM board since the console
is not connected to it.  What happens is that the console sends
a cntl-S to the system during the auto-configuration output.  
For some reason the systems loses the cntl-Q somewhere.  I fixed
the problem quickly (but not correctly) by slowing the console
to 1200 baud from 2400 baud.  I suspect that flushing the input
buffer for the console at the beginning of init would fix the 
problem.
