There is no DRM interaction going on at the time the machine reboots. Actually, it can reboot any time, even when completely idle. Sometimes it reboots on Xserver start. It doesn't occur on i686 hardware. It doesn't occur with 11.0's kernel 2.6.25.16. It doesn't occur with R5xx GPUs. As the used DRM module is the same, I assume this has something to do with memory or interrupt management. The following lines upon drm initialization hit my eye (in the crashing case): Sep 23 19:53:37 gkar kernel: [drm] Initialized drm 1.1.0 20060810 Sep 23 19:53:37 gkar kernel: pci 0000:01:00.0: BAR 0: can't reserve mem region [0xd0000000-0xdfffffff] Sep 23 19:53:37 gkar kernel: vendor=1022 device=9603 Sep 23 19:53:37 gkar kernel: pci 0000:01:00.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18 Sep 23 19:53:37 gkar kernel: pci 0000:01:00.0: setting latency timer to 64 Sep 23 19:53:37 gkar kernel: [drm] Initialized radeon 1.29.0 20080613 on minor 0 With 2.6.25, the following is printed instead: Sep 23 20:18:25 gkar kernel: [drm] Initialized drm 1.1.0 20060810 Sep 23 20:18:25 gkar kernel: PCI: Unable to reserve mem region #1:10000000@d0000000 for device 0000:01:00.0 Sep 23 20:18:25 gkar kernel: ACPI: PCI Interrupt 0000:01:00.0[A] -> GSI 18 (level, low) -> IRQ 18 Sep 23 20:18:25 gkar kernel: PCI: Setting latency timer of device 0000:01:00.0 to 64 Sep 23 20:18:25 gkar kernel: [drm] Initialized radeon 1.29.0 20080613 on minor 0 I'd need some advice how to debug this issue. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
