Dear all: Recently I met some problem while enable drm function. Each time when I call drmAgpBind, defined in Xf86drm.c, OS will either hang or reboot so fast that it doesn't leave any log, including XFree86.0.log or /var/log/messages. By the way, I have elevated the kernel message-level to KERN_ALERT. Below I list some test I have done: 1. if I mark drmAgpBind, I can see all messages I add in XFree86 and kernel drm functions. 2. if I call the drmAgpBind before drmAgpAlloc, I can see the unbind message reported by kernel. (I change the order purposely to make sure whether the function works, and it seems work.) The kernel version I have tried is 2.4.19, 2.4.20 with XFree86 4.3. My vga card is SiS315Pro, and I know the present driver not support DRI. But OS will report the error message instead of crashing or hanging, right? By the way, except /var/log/messages, where can I see the messages printed by kernel, I mean maybe there are another place record the answers I need but I don't know where it is. Thanks for your patience after reading my problems. If you have any comment, please let me know. Sincerely Yours, Pierre _______________________________________________ XFree86 mailing list XFree86@xxxxxxxxxxx http://XFree86.Org/mailman/listinfo/xfree86
