Public bug reported: My computer freezes very, very frequently. I'm using 12.04.02 (32bit, though my computer supports 64 bit, but I had freezes with that too), I've had the same trouble on 12.04.01 and 12.10. I've used kernels 3.2, 3.5 and 3.8, all still have freezing. I'm not sure how to identify the package causing the freezing, but not for a lack of trying. If anyone has any idea, I will cheerfully supply whatever info you need. It's been close to two months I think. :P
When it freezes, the keys do not respond at all, making another tty or using REISUB completely impossible. It can happen anywhere from a few seconds to a few hours after a boot. Usually while browsing, but that's because I'm usually browsing I think. The only thing I can do is a hard reset. I have tried to ssh into my computer from my wife's, but it is impossible while frozen (note, it IS possible when my computer is not frozen, so from what I have read, this indicates my error is not a GPU hang, correct me if I am wrong :) ) Memtest shows no errors (memtest would not run, except for from a live usb, but I got it covered. No errors). Happens in unity 2d and unity 3d, guessing it's not compiz. No proprietary drivers either. My computer is kept dust free, it is not overheating. As per another report, I tried noapic and nomodeset, to no avail. acpi=off too. :P acpi_apic_instance=2 did not work better either. joe@Sutarmekeg:~$ lspci 00:00.0 Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 03) 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 03) 00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (secondary) (rev 03) 00:1a.0 USB controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #4 (rev 03) 00:1a.1 USB controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #5 (rev 03) 00:1a.7 USB controller: Intel Corporation 82801H (ICH8 Family) USB2 EHCI Controller #2 (rev 03) 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) 00:1c.0 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 1 (rev 03) 00:1c.1 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 2 (rev 03) 00:1c.2 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 3 (rev 03) 00:1c.3 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 4 (rev 03) 00:1c.4 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 5 (rev 03) 00:1d.0 USB controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #1 (rev 03) 00:1d.1 USB controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #2 (rev 03) 00:1d.2 USB controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #3 (rev 03) 00:1d.7 USB controller: Intel Corporation 82801H (ICH8 Family) USB2 EHCI Controller #1 (rev 03) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev f3) 00:1f.0 ISA bridge: Intel Corporation 82801HM (ICH8M) LPC Interface Controller (rev 03) 00:1f.1 IDE interface: Intel Corporation 82801HM/HEM (ICH8M/ICH8M-E) IDE Controller (rev 03) 00:1f.2 SATA controller: Intel Corporation 82801HM/HEM (ICH8M/ICH8M-E) SATA Controller [AHCI mode] (rev 03) 00:1f.3 SMBus: Intel Corporation 82801H (ICH8 Family) SMBus Controller (rev 03) 02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8039 PCI-E Fast Ethernet Controller (rev 14) 03:00.0 Ethernet controller: Atheros Communications Inc.
