Description Stephen Adler 2004-12-06 16:19:25 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1)

Description of problem:
I loaded an AMD64 system with fc3 and Matrox G450 card installed.
The install went fine, the system booted fine, and system was fully
operational. I then switched out the Matrox G450 card for an ATI
FireGL X1 card, (x8 AGP), and when the system boots, it hangs during
rc.sysinit when the script is running sysctl. At this point,
I can issue a ^C and the system continues booting (i.e. soft
hang) but this breaks out of rc.sysinit and does not finish
executing some important code, (i.e. like remounting the
file systems in read/write mode.) The system becomes non-operational.

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

How reproducible:

Steps to Reproduce:
1. Load fc3 on an amd64 system and a ATI FireGL x1 card
2. Try and boot...

Comment 1 Karel Zak 2004-12-07 13:06:05 UTC
sysctl is called more times in rc.sysinit, when it hang up? During
"Configuring kernel parameters: ..."?

What do you have in the file /etc/sysctl.conf?

Can you try after complete boot do as root:

   # sysctl -e -p /etc/sysctl.conf

Comment 2 Stephen Adler 2004-12-07 14:39:31 UTC
yes, its during the "Configuring kernel parameters: ...". The problem
is that I can't boot into an operational state since the system
hangs at the "Configuring kernel parameters:..." state. Do you know
how I can boot up without it configuring the kernel? Is there a
way to disable this step during boot up?

Comment 3 Karel Zak 2004-12-08 17:29:56 UTC
You have to boot to "emergency" mode, see: 


and edit the file /etc/rc.d/rc.sysinit. At line cca 234 you can found

action $"Configuring kernel parameters: " sysctl -e -p /etc/sysctl.conf

please, disable this line by '#'

Now you can try boot to standard mode.

Any progess with FC4?

Comment 5 Karel Zak 2005-10-20 12:42:22 UTC
Since there are insufficient details provided in this report for
us to investigate the issue further, and we have not received the
feedback we requested, we will assume the problem was not

reproduceable, please REOPEN this big report.
