From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 Description of problem: Kernel panics regularly after several hours (less than one day), when the machine is not in use. Since the screen is blank, the only indication of the panic is flashing caps/scroll lock keys. Same behavior seen in 667 and 673. I notice the following as the last entry in /var/log/messages before the panic: Dec 9 04:33:09 lucy-01 netplugd[2459]: eth0: state ACTIVE flags 0x00001043 UP,BROADCAST,RUNNING,MULTICAST -> 0x00001003 UP,BROADCAST,MULTICAST Dec 9 04:33:09 lucy-01 netplugd[8189]: /etc/netplug.d/netplug eth0 out -> pid 8189 Dec 9 04:33:09 lucy-01 netplugd[2459]: eth0: state OUTING flags 0x00001003 UP,BROADCAST,MULTICAST -> 0x00001002 BROADCAST,MULTICAST Dec 9 04:33:09 lucy-01 netplugd[2459]: eth0: state DOWNANDOUT pid 8189 exited status 0 Dec 9 04:33:09 lucy-01 netplugd[8232]: /etc/netplug.d/netplug eth0 probe -> pid 8232 Dec 9 04:33:09 lucy-01 netplugd[2459]: eth0: state PROBING flags 0x00001002 BROADCAST,MULTICAST -> 0x00001043 UP,BROADCAST,RUNNING,MULTICAST Dec 9 04:33:09 lucy-01 netplugd[2459]: eth0: state PROBING_UP pid 8232 exited status 0 The above netplugd output doesn't occur when running with a single processor (nor does the panic). Version-Release number of selected component (if applicable): 2.6.9-1.681_FC3smp How reproducible: Always Steps to Reproduce: 1.Boot to level 5 2.Log in 3.Wait. Actual Results: System panics Expected Results: Don't panic Additional info: This problem does not occur if I disable the second processor. Thus, seems to be MT-related. Whether hyperthreading is enabled or not doesn't seem to matter. Machine is a Dell Workstation 530n, with 2 x Xeon 2Ghz, 1GB memory, 1 40GB IDE disk, a 18GB U160 SCSI disk hosting FC3, and a 73GB U160 SCSI disk w/ data. A nightly dump (/sbin/dump) occurs to a DDS4 scsi tape drive (always succeeds, finishes in a few minutes after 2am). The IDE disk running, but not mounted. The scsi controller is an Adaptec 29160 add-on card. Onboard scsi is disabled. 19> lspci 00:00.0 Host bridge: Intel Corp. 82860 860 (Wombat) Chipset Host Bridge (MCH) (rev 04) 00:01.0 PCI bridge: Intel Corp. 82850 850 (Tehama) Chipset AGP Bridge (rev 04) 00:02.0 PCI bridge: Intel Corp. 82860 860 (Wombat) Chipset AGP Bridge (rev 04) 00:1e.0 PCI bridge: Intel Corp. 82801 PCI Bridge (rev 04) 00:1f.0 ISA bridge: Intel Corp. 82801BA ISA Bridge (LPC) (rev 04) 00:1f.1 IDE interface: Intel Corp. 82801BA IDE U100 (rev 04) 00:1f.2 USB Controller: Intel Corp. 82801BA/BAM USB (Hub #1) (rev 04) 00:1f.3 SMBus: Intel Corp. 82801BA/BAM SMBus (rev 04) 00:1f.4 USB Controller: Intel Corp. 82801BA/BAM USB (Hub #2) (rev 04) 00:1f.5 Multimedia audio controller: Intel Corp. 82801BA/BAM AC'97 Audio (rev 04) 01:00.0 VGA compatible controller: nVidia Corporation NV11GL [Quadro2 MXR/EX] (rev b2) 02:1f.0 PCI bridge: Intel Corp. 82806AA PCI64 Hub PCI Bridge (rev 03) 03:00.0 PIC: Intel Corp. 82806AA PCI64 Hub Advanced Programmable Interrupt Controller (rev 01) 03:0c.0 SCSI storage controller: Adaptec AIC-7892A U160/m (rev 02) 04:0b.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 78) 20> I'm running the userland nv display driver.
can you disable the screen blanking to try and capture the panic ?
I've gone on to later kernels (760 lately), and am now using nvidia's driver. I'm not (and haven't) experienced this panic for some time now, so apparently this problem no exists. Go ahead and close it.
