*** This bug has been marked as a duplicate of bug 517625 *** Sorry, not a duplicate of bug #517625. That user has NV: Found NVIDIA GeForce FX Go5650 at 01@00:00:0 with (II) Loading sub module "xaa" His is a totally different problem. Retested with: kernel-2.6.31.1-58.fc12.i686 xorg-x11-server-common-1.7.0-1.fc12.i686 xorg-x11-drv-ati-6.13.0-0.7.20091006git457646d73.fc12.i686 libdrm-2.4.14-1.fc12.i686 mesa-libGL-7.6-0.13.fc12.i686 As far as I can tell the problem has disappeared. I've now been using the machine for several hours and still no lockup. |
Description of problem: X hangs regularly on my Lenovo T60 with Mobility Radeon X1300 [1002:7149] since I pre-upgraded from F11 to F12-rawhide. As far as I can see there is no specific action to trigger it. When it happens the mouse pointer movement becomes jerky and there are no X display updates anymore. The system itself is not frozen, i.e. you can still initiate a ACPI powerdown with the power off key or login with ssh and initiate a shutdown command. Version-Release number of selected component (if applicable): xorg-x11-drv-ati-6.13.0-0.4.20090908git651fe5a47.fc12.i686 libdrm-2.4.12-0.10.fc12.i686 mesa-libGL-7.6-0.11.fc12.i686 kernel-2.6.31-23.fc12.i686 xorg-x11-server-Xorg-1.6.99.901-2.fc12.i686 How reproducible: always Steps to Reproduce: 1. Login as normal user into X session 2. work normally, e.g. browse web pages Additional info: Smolt URL attached 1. I'm using kernel parameter "nomodeset" as KMS breaks suspend 2. I have experienced the freeze after a fresh boot and after resume from hibernate 3. I have experienced the freeze with WLAN active or not active 4. I have experienced the freeze with cable Ethernet active or not active 5. Log in after the fact shows the X process uses up 100%, i.e. one CPU core 6. X process can only be killed with -9 7. Killing X does NOT restore the display, chvt hangs 8. uname -a: Linux XXX 2.6.31-23.fc12.i686 #1 SMP Wed Sep 16 16:09:25 EDT 2009 i686 i686 i386 GNU/Linux 9. There are no messages in /var/log/Xorg.0.log from the point in time when the freeze occurs 10. Don't know if this is related, but after a fresh boot I get these dmesg when X starts: ======================================================= [ INFO: possible circular locking dependency detected ]
