Comment 16 for bug 204996

Yeah, same thing here, hard lockups every two to four hours. Thing goes totally dead.

Hardware: Acer 3680 laptop, Celeron single-core 1.6gHz, 533 memory bus, Atheros WiFi, 80gig SATA hard disk, 1.5gigs memory, Intel945 video, Intel sound, Marvell Ethernet chipset. This thing ran great under Gutsy and Feisty, no signs of overheating. I briefly switched back to Gutsy and all lockups vanished. My usually Internet connection is a Verizon EVDO cellmodem, Kyocera KPC650 PCMCIA set up as a PPP device, but I'm also crashing with it pulled so that's not it.

Software: pretty basic Hardy setup, also VirtualBox 1.5.6. Most crashes have happened without running a guest OS (XP).

Things I've tried: disabling Compiz, disabling Powernowd, pulling the Atheros miniPCI card completely, switching from Network Manager to Wicd, disabling Tracker completely, various others. Nothing has helped.

Version.log file (as described above) contains:

Ubuntu 2.6.24-16.30-generic

dmesg.log file is attached to this post, the last log will go in next.
