Crash: XFree86 4.0.3 and Kernel 4.0.3

I hate to report this again, I saw some reports that it was fixed with 4.0.3 of XFree86, so I tried XF86 4.0.3 with RedHat 7.1.

Any time it tries to turn the monitor off, it crashes. I get no oopses. Nothing.

Has anyone figured out why it crashes? How can I fix it besides remove the power savings option of automatically shutting the monitor off? BTW, I am running this box with ACPI. It crashes even more if I use APM. I never could figure that out, but anyway.

Hi Trevor,

I have the same problem with almost the same combination (RH 7.0 instead of RH 7.1). Did you compile the XFree server yourself and if so, did you optimize it for i686? The reason why I'm asking is that I did that and suspected the optimazions to cause the crashes.

Juri, et al.

I did some searches on google. It seems that it is the combination
of kernel 2.4, glibc2.2.x, and possibly the i686 optimizations. I found my machine was alive from a network connection. The problem is, I cant get my keyboard back even with sysrq (syslog does show it changing into XLATE mode... I thought alt-ctrl-r was raw?). Of course the machine was alive, but X was dead. xscreensaver and the screen save it ran along with most of the desktop stuff was still running.

Anyway, I tried 'shutdown -r now'over the network. Didn't work. I had
to do a hard reset. So it seems the kernel may be slightly left in an unknown or confused state.

I did not compile it myself. Using RedHat 7.1 standard.

Since I saw this mentioned here recently, does gcc still think 686=cmov? If so, Alan or someone else, does Athlon classic (slot 800 Mhz) support cmov?

We'll need patches to check on this... our current kernel is just 2.4.4-pre5

Sorry, I should have sent a message correcting myself as soon as I realized I did that. Moral of the story, never post when you just woke up. That is kernel 2.4.3.

Sorry again,
