Description Tom Wood 2005-03-17 09:23:22 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050302 Firefox/1.0.1 Fedora/1.0.1-1.3.2

Description of problem:
Boot process stops and screen goes blank when booting kernel-smp while running in /etc/rc.sysinit at "Initializing hardware" just after "audio" comes up.

There is no audio hardware in this machine.  It's a dual processor P III running on a Via 686 chipset (Abit VP6).

This machine ran fine under RH9 - FC3.  This is a fresh install of FC4t1.

System at this point hard locks, sysrq doesn't respond.

UP kernel works.

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

How reproducible:

Steps to Reproduce:
1. Boot the kernel-smp.
2. Watch system lock up.

Actual Results:  Hard lock as described above

Expected Results:  System should have booted.

Comment 6 Tom Wood 2005-03-17 16:40:11 EST
The lockups and bad behaving video are caused by a segfaulting matroxfb-base
module.  This doesn't segfault in the UP kernel, just the SMP kernel.  I
disabled the "other" category in /etc/rc.sysinit around line 210 or so and
manually modprobed the modules it specified.  The others (parport_pc and
uhci-hcd) were fine.

Please see the last two attachments for details from lsmod.

Comment 8 Tom Wood 2005-03-21 10:01:28 EST
Still exists in 1191 kernel.
Comment 9 Tom Wood 2005-03-25 14:41:10 EST
Still exists in 1202 kernel.
Comment 10 Tom Wood 2005-03-29 11:11:15 EST
Still no matrox love in 1208 SMP kernel.
Comment 11 Tom Wood 2005-03-31 16:00:49 EST
The 1219 kernel is worse.  Now the UP kernel also hangs in the same spot.
Comment 12 Tom Wood 2005-04-04 14:22:11 EDT
Works fine now in 1225 kernel, UP and SMP both.  Get a rather disconcerting font
change and a momentary blinking out of the video, but that's to be expected.

I have a similar problem on my machine.  It boots up, then starts loading the
GUI, and gets as far as 'setting hostname'.  Then the display goes black.  There
is still a signal to the screen, because the LED stays green, but there's no
display, and no mouse curser.

I have to reboot several times to get any further than this.  I know it's not
booting any further, because I can't SSH into it.  It does however show up in my
DHCP table.

I'm running Fedora Core 2, 2.6.11-1.14_FC3, on a Pentium 3, 500MHz, AOpen AX6BC
motherboard with the latest bios, 256MB ram, PA700 pro display adapter.  If I
can get it to boot any further, I might be able to get more system info.

Mass update of -test bugs to update version to fc4.
(Please retest on final release, and report results if you have not already done
