Description jimomura 1999-02-22 13:10:54 EST
I recently posted messages to the "linux.setup" newsgroup
but I have had no helpful responses.  This may be a problem
in the Kernel itself or perhaps in the RPM files, or
related "SysVinit" or "initscripts" files:

In a couple of previous messages I reported I was having
using an external Modem on COM2 when I upgraded to Kernel
2.0.36-1.  I've continued to work on the problem without

I downloaded the latest Kernel version 2.0.36-3 files.  I
them with "rpm -Uvh --force".  The same COM2 problem showed
I then checked "initscripts" and "SysVinit" and found that I
had the latest 5.1 versions (SysVinit 2.74-4 and initscripts
I tried to install the 5.2 versions ("SysVinit 2.74-5" and
"initscripts-3.78-1") using

rpm -Uvh --force

but the result was:

failed dependencies:
       redhat-release <= 5.1 conflicts with initscripts-

Since the installation failed, I did not re-install 2.0.35-2
it should be intact.  Any suggestions would be welcome.

Earlier Message:

I've been reading Mark Bratcher's problems regarding RH
Linux 5.2
and his internal COM2 modem and I think there may be a more
problem with the 2.0.36 Kernel.

I'm running a Gigabyte 5486AL motherboard (486DX4/100).  I
have a
mouse on COM1 and my external modem on COM2.  I started out
with RH
Linux 5.1 which comes with Kernel version 2.0.35-1 and I've
using it as a remote client to my ISP through "Network
PPP through /dev/modem on COM2.  I've been stepping my way
upgrades one at a time, so I previously upgraded to Kernel
2.0.35-2 without problems.  However, yesterday I tried
to Kernel version 2.0.36-1 and I could no longer dial out.
you click on "activate" the modem DTR light would come on
for a
moment and then turn off.  It was on for about a 1/4 second.
checked the "Network Configurator" settings and everything
to be ok.  I tried "a few other things" but nothing seemed
help.  So I eventually reloaded Kernel version 2.0.35-2 and
working again.

Does anybody have an suggestions for setting changes?  Does
know of any other problems on the serial ports?

The following is some further information:

Last upgrades just before the Kernel upgrades:

Upgraded "pam" to "pam-0.64-4.i386.rpm" version
Upgraded "ftp" to "ftp-0.10-4.i386.rpm" version

Things I noticed while running with Kernel version 2.0.36-1:

1.  I think I saw some references to 2.0.35 stuff during the
boot.  This is hard to tell since some of the boot messages
go by
pretty fast for human eye reading on a DX4/100.  Is there a
way to
store this as a text file?  Is it already being stored

2.  After 2.0.36-1 upgrade, the "finding module
dependencies" during
system boot was still looking for 2.0.35-2 dependencies.
is definite.

3.  Also, system boot page still refers to 2.0.35 kernel.
latter is probably not relevant since it's probably just a
text file
somewhere that's printed to the tty before the login.

Reinstalling Kernel version 2.0.35-2:

The following errors were returned by rpm:

"cannot remove /lib/modules/2.0.36-1/misc - directory not
"cannot remove /lib/modules/2.0.36-1 - directory not empty"
"cannot remove /usr/src/linux-2.0.36 - directory not empty"
"package /usr/src/linux-2.0.36/drivers/block/ali4xx.c not
found in
file index"

I also tried addressing "/dev/ttyS1" instead of "/dev/modem"
"Network Configurator".  That made no difference.  However,
had no problem using the COM2: port.
Comment 1 jimomura 1999-06-21 16:17:59 EDT
Last week I upgraded to RHL 6.0.  The complete upgrade had
no problem using the Network Configurator PPP through /dev/modem.
I think that if I'd done a full system upgrade to 5.2, that would
have fixed it too.

     A similar problem is now occurring after upgrading RHL 6.0
from the supplied 2.2.5-15 Kernel to the 2.2.5-22 Kernel, but
I'll submit a new bug report for that one separately.

     Note that the "finding module dependencies" problem also
did not occur after the full upgrade to RHL 6.0
