Most recent kernel where this bug did not occur: Distribution: Debian Release: 3.1 Hardware Environment: Pentium-IV with Intel 865G Integrated graphics Software Environment: i686 linux, XFree86--Debian 4.3.0.dfsg.1-14sarge1 Problem Description: While running stellarium 0.8.0-2 compiled from Debian/Testing source in the 1280x1024 resolution, the system almost entirely locks up after a while of using it. The mouse Cursor vanishes. Standard keystrokes like 'ctrl-alt-backspace' or 'ctrl-alt-F1' to reach Console fails. However 'SYSrq' keys works, and the 'Powerbutton' can also signal 'init' to make a clean shutdown. he reason of the problem appears to be what I find in the kernel log. ------ Jul 16 19:17:07 localhost kernel: [17183280.920000] [drm:i830_wait_ring] *ERROR* space: 119528 wanted 131064 Jul 16 19:17:07 localhost kernel: [17183280.920000] [drm:i830_wait_ring] *ERROR* lockup Jul 16 19:17:30 localhost kernel: [17183303.920000] [drm:i830_wait_ring] *ERROR* space: 119384 wanted 131064 Jul 16 19:17:30 localhost kernel: [17183303.920000] [drm:i830_wait_ring] *ERROR* lockup --------------- I have seen the same problem happening with kernel-2.6.16.1 which I compiled after downloading from 'kernel.org'. output of 'lspci': ----------------------- 0000:00:00.0 Host bridge: Intel Corp. 82865G/PE/P DRAM Controller/Host-Hub Inte rface (rev 02) 0000:00:02.0 VGA compatible controller: Intel Corp. 82865G Integrated Graphics Device (rev 02) 0000:00:03.0 PCI bridge: Intel Corp. 82865G/PE/P PCI to CSA Bridge (rev 02) 0000:00:1d.0 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #1 (r ev 02) 0000:00:1d.1 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #2 (r ev 02) 0000:00:1d.2 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #3 (r ev 02) 0000:00:1d.3 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #4 (r ev 02) 0000:00:1d.7 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB2 EHCI Cont roller (rev 02) 0000:00:1e.0 PCI bridge: Intel Corp. 82801 PCI Bridge (rev c2) 0000:00:1f.0 ISA bridge: Intel Corp. 82801EB/ER (ICH5/ICH5R) LPC Bridge (rev 02 ) 0000:00:1f.1 IDE interface: Intel Corp. 82801EB/ER (ICH5/ICH5R) Ultra ATA 100 S torage Controller (rev 02) 0000:00:1f.2 IDE interface: Intel Corp. 82801EB (ICH5) Serial ATA 150 Storage C ontroller (rev 02) 0000:00:1f.3 SMBus: Intel Corp. 82801EB/ER (ICH5/ICH5R) SMBus Controller (rev 0 2) 0000:00:1f.5 Multimedia audio controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) A C'97 Audio Controller (rev 02) 0000:01:01.0 Ethernet controller: Intel Corp. 82547EI Gigabit Ethernet Controll er (LOM) --------------- more '/proc/cpuinfo' shows: ---------- processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Pentium(R) 4 CPU 3.00GHz stepping : 1 cpu MHz : 2993.129 cache size : 1024 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe constant_tsc up pni monitor ds_cpl cid xtpr bogomips : 5991.35 ------------------ more '/proc/meminfo' shows: --------- MemTotal: 1019744 kB MemFree: 723692 kB Buffers: 20208 kB Cached: 178760 kB SwapCached: 0 kB Active: 126216 kB Inactive: 131280 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 1019744 kB LowFree: 723692 kB SwapTotal: 2104504 kB SwapFree: 2104504 kB Dirty: 0 kB Writeback: 0 kB Mapped: 82156 kB Slab: 14184 kB CommitLimit: 2614376 kB Committed_AS: 129564 kB PageTables: 784 kB VmallocTotal: 262136 kB VmallocUsed: 7976 kB VmallocChunk: 254112 kB ------------- Steps to reproduce: Run stellarium in 1280x1024 mode, move the cursor for a few minutes and try to switch on the 'azimuth grid' or so on by using the mouse, the machine appear to hang and would not respond with standard keystrokes (sysrq works).
