Hi, I recently installed Fedora Core 3 and I'm having a problem with X. Periodically it just shuts down. I can log in remotely when this happens (mostly) and see that X is sucking up 99% of the cpu. I get a "Receiving no signal" error from the monitor. I am running the x86_64 version of FC3. My hardware: ----------------------------------------------------------- Motherboard: Gigabyte GA-K8NS Ultra 939 Processor: AMD Athlon 64 3200+ RAM: 512MB PC3200 DDR SDRAM Hard drive: Western Digital WD1600JD 160GB SATA DVD: NEC ND-3500A ----------------------------------------------------------- No problems on the installation. I've run the system under windows and it runs fine so it isn't a hardware problem. I downloaded the latest release from X.org, compiled and installed it (6.8.2). I did the following: [douglass@skinner log]$ diff Xorg.0.log.old Xorg.0.log 14c14 < (==) Log file: "/var/log/Xorg.0.log", Time: Sat Feb 12 17:04:56 2005 --- > (==) Log file: "/var/log/Xorg.0.log", Time: Sat Feb 12 17:11:21 2005 999,1000d998 < (II) RADEON(0): [drm] removed 1 reserved context for kernel < (II) RADEON(0): [drm] unmapping 8192 bytes of SAREA 0xffffff0000068000 at 0x2a9d70e000 between a log when it crashed and the current log. Any tips on: 1) Where to start looking for the problem. 2) Anyone else seeing this? I've looked through the other logs and seen similar problems but no answers. Thanks in advance.
