Brian,

There is still some application or device that is causing this. I have 4 computers with all the Windows OS, I can run for days on any without seeing that high of a DPC, and PowerSDR not stopping.. Maybe Tim has a good suggestion with the BIOS update, but I am not sure how to update the BIOS on the MacBook.. Sorry, no fruit here.. Hi Hi . NIC drivers are the worst, make sure to stop the network, and make sure that you have disabled the "1394 Network" under network adapters if there is one showing up in Device Manager. I have roughly 35 to 42 processes showing on any of the OSs here.

And I am trying to get a different machine to run powerSDR reliably.
Every hour or so, out of the blue, I get a DPC latency spike of
43000us. Needless to say, PSDR stops working until I cycle it.

FWIW, everything is turned off, even ethernet. If I turn off any more
service tasks things stop working. But still I get that killer latency
spike. The rest of the time it is 500us.

Damn. There it goes again. Happened when I clicked on the Start button
this time. Wow a new record! 44,045us!

Look, I want so much for your products to work. No one else makes a
transceiver even remotely like the F5K. I can put up with the
inconsistent and wacky user-interface and not having a coherent
baseband signal output architecture. I roll my eyes but I can work
around them and use the radio. But the frustration of random failures
due to flaky system software is maddening. I shouldn't have to become
an OS tuning expert in order to use the radio.

PLEASEPLEASEPLEASEPLEASEPLEASEPLEASEPLEASEPLEASE SUPPORT ANOTHER OS
FOR THE FLEX PRODUCTS!!!!

Gawd I *hate* Microsoft Windows.
