Description Bruno De Wolf 2003-10-27 09:02:47 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1) Gecko/20031009

Description of problem:
Boot process hangs in rc.sysinit at 'devlabel'. 

1. If I boot with option 'pci=off', the system boots, but my usb mouse does not
function. Moreover, I can not load my usb-related modules in this case (insmod
usb-uhci fails).
2. If I boot with normal options, the boot process hangs in rc.sysinit at
'devlabel' execution. If I comment this out, rc.sysinit hangs at other steps
(like soundcard detection or at the 'clean op old files' section). Behaviour is
similar for booting in runlevels 1, 3 and 5.

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

How reproducible:

Steps to Reproduce:
1. Just boot the system with normal start-up parameters

Actual Results:  System hangs. No visible activity anymore. Keyboard and mouse
do not respond.

Expected Results:  Boot process should proceed without errors.

Additional info:

1. Basic hardware config: packard bell (NEC), Intel P4, 1.7 Gh, 256Mb RAM.
Nvidia graphics card, usb mouse & keyboard. Modem and ethernet card present.

2. I also have a Redhat 7.3 system on the same computer which I kept up to date
and which still works as desired. I can boot FC 0.95 with the last Redhat 7.3
kernel (2.4.20-20.7) without problems.

3. I had the same behaviour with fc0.95test3 with the original kernel (2088). I
updated this morning to kernel 2108 and latest initscripts and kernel utils via
rawhide, but I didn't see any improvement.

4. I am not a hardware expert. You can ask me to send additional info, but
please give some details on the commands to issue and the points to check.

Comment 1 Bruno De Wolf 2003-10-30 09:32:50 UTC
Just set my system completely up to date. Seems I'm still having the same
problem with kernel-2.4.22-1.2111.nptl.

Kind regards,


Comment 2 Bruno De Wolf 2003-10-30 15:35:27 UTC
Seems I was a bit too early and updated just before the release 1 came out.
Anyway, I downloaded kernel-2.4.22-1.2115.nptl, which still gives me the same

Kind regards,

Comment 3 User Reg 2003-12-11 08:44:07 UTC
I've similar problem on a Dell 2650 (3.2GHz, 1GB RAM) running Fedora 
Core.  I tried kernel-2.4.22-1.2115.nptlsmp and 2.4.23 (from 
source).  The results were the same.  However, everything works fine 
if booting from a kernel without SMP support (kernel-2.4.22-

Any update ?

Best Regards,

Comment 4 Bruno De Wolf 2003-12-18 20:12:31 UTC
I did some testing with the latest kernel (2.4.22-1.2129.nptl) on my
machine. Most of the times, my system now hangs at 'depmod'.
Sometimes, depmod goes fine and the system continous booting until the
'devlabel' part, where it always hangs.

The (latest?) kernel that doesn't cause troubles is 2.4.20-20.9, which
is the latest Redhat 9 kernel AFAIK.


Comment 5 Bruno De Wolf 2004-02-05 08:14:50 UTC

Some more information that might be usefull for you.
- I have a strong feeling that this bug is related to bugs 87977 and 
even 91264.
- Booting without my usb keyboard and mouse attached works fine with 
the 2.4.22-1.2149.nptl kernel. But booting with usb keyboard and 
mouse hangs the system.
- Arjan suggests that this might be a bios related issue, but I never 
experienced problems with 2.4.20 kernels and I always have the 
problem with all the 2.4.22 kernels I tested.
- Also, there's the problem explained with nvidia chipsets. But on my 
computer, only the VGA card is from nvidia (see lspci output - though 
I'm not a hardware expert). How can a graphics card have an influence 
on usb devices?

I would be happy to have some related feedback from people who know 
more on this issue than I do.

Kind regards,



Comment 6 Bruno De Wolf 2004-03-04 16:45:24 UTC
Did some more testing with the 2.4.22-2174 kernel.

Here is the scenario:
- boot without usb mouse and keyboard
- plugin mouse & keyboar
---> system hangs after a couple of seconds

Here is the system log:

Comment 7 Bruno De Wolf 2004-03-15 12:28:55 UTC
After some more testing, this problem is traced down to my USB
keyboard. I just compiled a vanilla 2.4.25 and booted with
init=/bin/sh - and the system hangs when plugging in the keyboard.

I also posted this problem in the linux-usb mailing list. Who is the
best person/organization to contact to continue the work on this? 

Thanks for your feedback.

Comment 9 Bruno De Wolf 2004-03-23 10:52:19 UTC
Thanks Pete,

This solves the problem indeed. I both tested this patch on the fedora
2174 kernel as on a vanilla 2.4.25 kernel. Without the patch, the
system hangs, with the patch, the system goes fine.

Thank you (and the others) for your work on this.

Kind regards,


Comment 11 David Lawrence 2004-09-29 19:35:01 UTC
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
