lsmod after modprobing matroxfb-base
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. Created attachment 112113 [details]
stack trace of the failed "modprobe matroxfb_base"
Still exists in 1191 kernel. Still exists in 1202 kernel. Still no matrox love in 1208 SMP kernel. The 1219 kernel is worse. Now the UP kernel also hangs in the same spot. 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 so). Thanks. |
