No. It is happening at the GUI while doing simple things ie playing mine sweep, or using firefox. It even occurs if nothing is loaded. It is random, but i have noticed it happens more, the longer the computer is powered up. When I reboot the problem goes away. Sometimes I can spend hours on line with no problem. I let the PC set a few hours and come back and the problem starts or doesn't.

I have since removed Ubuntu from 1st ("dual boot") PC in order to test Solaris 11.

That sounds reasonable to me, but what do I know.

There is one file in /proc/acpi named wakeup. I don't understand it's contents...

USB3 S3 *enabled pci:0000:00:1d.3

/sys has numerous items.

I disabled suspend and haven't experienced the problem. I'm not saying that is the cause.

I installed Solaris on the other PC that had same problem with Ubuntu and it doesn't have that issue any longer.

Thank you folks for your feed back. When I get WIFI working on Solaris, I think I'll 86 Ubuntu. I prefer Solaris's layout.

dahdi_hardware

DAHDI_HARDWARE(8)					User Contributed Perl Documentation					 DAHDI_HARDWARE(8)

NAME

       dahdi_hardware - Shows Dahdi hardware devices.

SYNOPSIS

       dahdi_hardware [-v][-x]

OPTIONS

       -v  Verbose ouput - show spans used by each device etc. Currently only implemented for the Xorcom Astribank.

       -x  Show disconnected Astribank unit, if any.

DESCRIPTION

       Show all dahdi hardware devices. Devices are recognized according to lists of PCI and USB IDs in Dahdi::Hardware::PCI.pm and
       Dahdi::Hardware::USB.pm . For PCI it is possible to detect by sub-vendor and sub-product ID as well.

       The first output column is the connector: a bus specific field that shows where this device is.

       The second field shows which driver should handle the device. a "-" sign marks that the device is not yet handled by this driver. A "+"
       sign means that the device is handled by the driver.

       For the Xorcom Astribank (and in the future: for other Dahdi devices) some further information is provided from the driver. Those extra
       lines always begin with spaces.

       Example output:

       Without drivers loaded:

	 usb:001/002	    xpp_usb-	 e4e4:1152 Astribank-multi FPGA-firmware
	 usb:001/003	    xpp_usb-	 e4e4:1152 Astribank-multi FPGA-firmware
