These happen a lot, seem not to be dependent on room temperature. The CPU fan works, I have de-dusted it, the case is open and still. There is a "temp1 at 55 c listed on PCI adapter. It seems rock steady, too steady! I can get it to 59-60 on a heavy 3d hw-accelerated graphics game. Maybe this sensor is on the nvidia pci-express card, not the cpu! Others, listed on ISA adapter, m/b, cpu, temp3 are all "disabled," possibly because of bios settings or problems. The fan itself, speed not sensored either, has its own thermostat, evident on cold days. These messages are annoying, the "throttling," if real, is a problem, but seem spurious. > [...] > > > [22172.918562] [drm] nouveau 0000:01:00.0: Setting dpms mode 0 on vga > > encoder (output 0) [22296.194815] CPU0: Core temperature above > > threshold, cpu clock throttled (total events = 1694) [22296.194841] > > CPU1: Core temperature above threshold, cpu clock throttled (total > > events = 1694) [22296.195873] CPU1: Core temperature/speed normal > > [22296.195878] CPU0: Core temperature/speed normal > > [22349.988028] [Hardware Error]: Machine check events logged > > [22636.814452] CPU1: Core temperature above threshold, cpu clock > > throttled (total events = 5487) [22636.814478] CPU0: Core temperature > > above threshold, cpu clock throttled (total events = 5486) > > [22636.815515] CPU1: Core temperature/speed normal > > [22636.815521] CPU0: Core temperature/speed normal > > [22799.988028] [Hardware Error]: Machine check events logged > > [23002.995857] CPU1: Core temperature above threshold, cpu clock > > throttled (total events = 8649) [23002.995886] CPU0: Core temperature > > above threshold, cpu clock throttled (total events = 8648) > > [23002.997076] CPU1: Core temperature/speed normal > > [23002.997083] CPU0: Core temperature/speed normal > > [23100.000210] [Hardware Error]: Machine check events logged > > [23504.371700] CPU1: Core temperature above threshold, cpu clock > > throttled (total events = 9153) [23504.371723] CPU0: Core temperature > > above threshold, cpu clock throttled (total events = 9152) > > [23504.372762] CPU1: Core temperature/speed normal > > [23504.372768] CPU0: Core temperature/speed normal > > [23549.988022] [Hardware Error]: Machine check events logged > > [...] > > This time it keeps happening, until > > > [24835.817176] CPU0: Core temperature above threshold, cpu clock > > throttled (total events = 9596) [24835.817200] CPU1: Core temperature > > above threshold, cpu clock throttled (total events = 9597) > > [24835.818353] CPU1: Core temperature/speed normal > > [24835.818356] CPU0: Core temperature/speed normal > > [...] > > > [25049.988081] [Hardware Error]: Machine check events logged > > [...] > > > [25280.229943] usb 1-3: USB disconnect, device number 6 > > [25289.864027] usb 1-3: new high-speed USB device number 7 using ehci_hcd > > [25289.998233] usb 1-3: New USB device found, idVendor=1004, > > idProduct=618e [25289.998239] usb 1-3: New USB device strings: Mfr=1, > > Product=2, SerialNumber=3 [25289.998243] usb 1-3: Product: LG Android > > USB Device > > [25289.998246] usb 1-3: Manufacturer: LG Electronics Inc. > > Perhaps the machine was in a hot place at the same time as the phone > was plugged in.

If non-sound drivers are causing this problem, I would guess virtual box because it needs alsa for sound in its VMs. Further testing needed. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
