User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)

Description of problem:
I use the standard 6.2 install with updates from updates.redhat.com with 
no changes to the MAKEDEV and setserial rpms.
I replaced the standard 6.2 kernel with a generic 2.2.19 kernel from 
kernel.org. Then I tried to reset ttyS4, which my modem uses, using 
setserial and setserial says ttyS4 does not exist. 
I created ttyS4 using MAKEDEV and reset it with chmod and chgrp to 
standard ttyS? settings.
With the standard 6.2 kernel setserial resets ttyS4 every time.
I need the generic kernel to run the MOSIX cluster program.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.remove kernel-source
2.delete 2.2.14-5 directory in /lib/modules, and /usr/src if anything is 
3.untar kernel
4.recompile and install kernel

Actual Results:  # cd /dev
# ls ttyS4
# ttyS4
# setserial ttyS4
# ttyS4: No such device

Expected Results:  # setserial ttyS4

Additional info:

I have done this on 2 different computers with the same result.

/dev/lp0 has also become invisible to setserial, and also to printtool.

Comment 2 Tim Waugh 2001-10-15 11:01:08 UTC
We don't provide the generic kernel; we provide the one the worked.  Closing.
(What was wrong with the Red Hat-provided kernel in the first place?)

Comment 3 Need Real Name 2001-10-17 16:33:06 UTC
The MOSIX cluster program is no longer issued in rpm form. The generic version of MOSIX requires a generic kernel. The rpm kernel 
is unacceptable to the generic MOSIX installer.
I tried the generic kernel because I was under the impression that a generic kernel would work equally well. 
I looked at Piranha. It does not do what I want done. MOSIX does.
