Infrequently the screen will go black and the computer will be unresponsive (except to SysRq keys), after locking it with xlock (x11-misc/xlockmore). After looking through /var/log/messages, I've noticed an fglrx error complaining about an ASIC hang. This message is always exactly 3 minutes after the xlock start message. Reproducible: Sometimes The computer is remains pingable in this state and the lock shows that it continues to run cron jobs. I've tried upgrading the ati-drives, using both ATI's package from their website and x11-drivers/ati-drivers (currently 10.11). This problem has also persisted through kernel upgrades (2.6.34-gentoo-r12 to 2.6.36-gentoo-r5). lspci: 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07) 00:01.0 PCI bridge: Intel Corporation Mobile 4 Series Chipset PCI Express Graphics Port (rev 07) 00:03.0 Communication controller: Intel Corporation Mobile 4 Series Chipset MEI Controller (rev 07) 00:03.2 IDE interface: Intel Corporation Mobile 4 Series Chipset PT IDER Controller (rev 07) 00:03.3 Serial controller: Intel Corporation Mobile 4 Series Chipset AMT SOL Redirection (rev 07) 00:19.0 Ethernet controller: Intel Corporation 82567LM Gigabit Network Connection (rev 03) 00:1a.0 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4 (rev 03) 00:1a.1 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #5 (rev 03) 00:1a.2 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #6 (rev 03) 00:1a.7 USB Controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #2 (rev 03) 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03) 00:1c.0 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 1 (rev 03) 00:1c.1 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 2 (rev 03) 00:1c.2 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 3 (rev 03) 00:1c.4 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 5 (rev 03) 00:1d.0 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #1 (rev 03) 00:1d.1 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #2 (rev 03) 00:1d.2 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #3 (rev 03) 00:1d.7 USB Controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 (rev 03) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev 93) 00:1f.0 ISA bridge: Intel Corporation ICH9M-E LPC Interface Controller (rev 03) 00:1f.2 SATA controller: Intel Corporation ICH9M/M-E SATA AHCI Controller (rev 03) 01:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3400 Series 03:00.0 Network controller: Intel Corporation Wireless WiFi Link 5300 86:09.0 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller (rev 06) 86:09.1 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 25) 86:09.2 System peripheral: Ricoh Co Ltd R5C843 MMC Host Controller (rev 14) 86:09.3 CardBus bridge: Ricoh Co Ltd RL5c476 II (rev bb) /var/log/messages: Feb 7 11:51:15 dwlasalle xlock[20159]: Start: dwlasalle, dwlasalle, :0 Feb 7 11:54:15 dwlasalle kernel: [11744.313006] [fglrx] ASIC hang happened Feb 7 11:54:15 dwlasalle kernel: [11744.313011] Pid: 16906, comm: X Tainted: P W 2.6.36-gentoo-r5 #1 Feb 7 11:54:15 dwlasalle kernel: [11744.313013] Call Trace: Feb 7 11:54:15 dwlasalle kernel: [11744.313050] [<ffffffffa007d153>] KCL_DEBUG_OsDump+0x9/0xb [fglrx] Feb 7 11:54:15 dwlasalle kernel: [11744.313078] [<ffffffffa008a20c>] firegl_hardwareHangRecovery+0x1c/0x50 [fglrx] Feb 7 11:54:15 dwlasalle kernel: [11744.313127] [<ffffffffa01033d9>] ?

Sounds like an ati-drivers bug, which we're not able to handle. Hopefully fixed long ago at this point.
