Public bug reported: The system locks up at random. It may not lock for a day after booting up the machine. It may lock up after a few minutes of booting up the machine. Sometimes the display just freezes, displaying whatever was last being displayed on the monitor. Sometimes the monitor displays a solid color when locking up. The machine does not respond to pings nor any of the key combinations involving sysrq. The only way to recover is a hard reset.
The machine is running Kubuntu 12.04.2 LTS Release: 12.04 The computer is a HP Pavilion p6-2003w Desktop PC. The url giving its specs is below. http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c03052733&lang=en&cc=us&contentType=SupportFAQ&prodSeriesId=5151865&prodTypeId=12454 Motherboard AAHD2-HY (Holly) Manufacturer: Pegatron Form factor: uATX: 24.38 cm (9.6 inches) x 24.38 cm (9.6 inches) Chipset: AMD Hudson-D2 FCH Memory sockets: 2 x DDR3 Front side bus speeds: 100 MHz UMI (Unified Media Interface) Processor socket: FM1 Expansion Slots: PCI-Express Generation 2 speed 1 PCI Express x16 3 PCI Express x1 1 PCI Express Mini Card x1 Processor AMD E2 3200 Processor TDP: 65W Operating speed: Up to 2.4 GHz Number of cores: 2 Socket: FM1 Bus speed: 4.0 GT/s HT3 Memory 4 GB Amount: 4 GB Speed: PC3-10600 MB/sec Type: DDR3-1333 The above is the memory it came with. I have since added another identical 4GB. This upgrade did not affect the random lockup problem. Built in graphics AMD E-Series Processors E2-3200 HD 6370D 65W This is the on board graphics. I have added an NVIDIA geforce 210 1024MB card. This upgrade did not affect the random lockup problem. Sound/Audio Integrated Realtek ALC 656 Audio *Integrated audio is not available if a sound card is installed. Built-in High Definition 5.1 channel audio Audio codec: Realtek ALC 656 Networking LAN: 1000-Base-T Interface: PCI Express x1 Technology: Realtek RTL8111E gigabit ethernet controller Data transfer speeds: up to 10/100/1000 Mb/s Transmission standards: 1000-Base-T Ethernet I added an additional RTL8111 PCIe nic. This also did not affect the locking up issue. The machine came with windows7. I soon replaced it with XP. The random lockup bug didn't show itself until I replaced windows with Kubuntu. For a few weeks I tried Slackware 14.0 64bit and did not experience any problem with randome freezes during this time. When I reinstalled Kubuntu, the random lockup bug returned. Thanks for your help.
