Crash with 8756 driver &twinview
 
1 Attachment(s)
I have the Livna 8756 drivers installled on my Fedora FC5 system. With the old 8157 (?) driver I had Twinview working without any problems. When the update to the 8756 driver got installed the X windows system did crash.
I have an Asus A8N SLi de luxe motherboard with an XP 4200 processor. The 8756 driver works well when I do not enable TwinView. I have included the nvidia-bug-report.log created while running without TwinView.
Creating the bug report while running with Twinview enabled fails, due to a hang of the script. This appears to be caused by a kernel crash.
enclosed are the output from a ps while running the script, as well as the output from dmesg and the X logfile with TwinView enabled.

I have a few questions:
0) Does X crash immediately when TwinView is in use?
1) Which BIOS version are you using?
2) Does this reproduce if you boot with the 'nosmp' kernel parameter?

Thanks,
Lonni

hi Lonni,
thanks for your help. Here are the answers to your questions:
0) Does X crash immediately when TwinView is in use?
The graphical boot screen works as expected if enabled, as soon as the X-server is started, X crashes. It does not even show the Nvidia splash screen

1) Which BIOS version are you using?
I had bios 1013 dated 07/26/2005. On the Asus website I found a version 1016, dated 12/01/2005 and installed it. The crash remains the same

2) Does this reproduce if you boot with the 'nosmp' kernel parameter?
The machine does not even boot when I set teh nosmp parameter. It complains about lost interrupt on hda (a cdrom player). So I could not test this unfortunately

I'm not having any luck reproducing this problem on the Asus A8N motherboard that I have here.

Do you have the means of using a DVI to VGA adapter to test whether this reproduces in analog mode, instead of digital?

Additionally, can you try booting with the noapic and/or acpi=off kernel parameters?

Thanks,
Lonni

My apologies for the slow response, but I have been on a business trip most of the week.

Done...
I have now connected both monitors using a DVI => VGA and now it everything works as expected! :)
I also tried combinations of DVI and VGA. One crashes, the other works ok. I have included the bug report for the one that works ok.

I have tried with both options, and this makes no difference

thanks, Louis

I've reproduced this problem and opened a bug. It is specific to TwinView with two DFPs.

Thanks,
Lonni
