Hello, I noticed a thread in April, 2002 about DRI lockups people were seeing when using a Radeon card with the AMD 760MP chipset. I didn't see a resolution, though, and as I am seeing the same thing now, I wanted to ask what the status is.
I'm using a Radeon VE QY with a Tyan S2460 motherboard, and whenever I enable DRI, switching from a text console back to X causes X to lockup. (But the kernel is OK, I can use Alt-Sysrq.) The screen shows the expected contents except for a rectangle of garbage near the top. I don't have a different video card to try, but if I disable DRI, or if I use an AMD 760MPX based motherboard (Asus A7M266-D), the problem goes away. FWIW, the BIOS update pages on the Tyan S2460 and S2462 (the only AMD 760MP motherboards available) both show that earlier versions of the BIOS had a problem with Radeon cards reinitializing the display on warm boots. I don't know if this former 760MP + Radeon BIOS problem is related to the current 760MP + Radeon DRI problem. I noticed the following Changelog entry in the xfree86.org CVS: "114. Fixes for DRI lockup problems with Radeon 7500/VE and the AMD 761 chipset (Hui Yu@ATI)." Of course, the AMD 760MP uses the AMD 762 northbridge, but I thought this might be related. So I compiled the latest xfree86 CVS and tried it. I'm running kernel 2.5.15-dj2, so I also grabbed kernel 2.5.18, which includes a DRI CVS merge, and used the drivers/char/drm code from it to compile the kernel DRM module. Unfortunately, this combination still shows the lockups. Any other suggestions on what to try? Or is there further information I should provide? I noticed that in the April thread, the person reporting the problem eventually provide a trace from a static X server, but I didn't see a response after that. If it would be helpful to have another trace, I could try to capture one. Thanks, Wayne _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
