Re: [Flexradio] Freeze-ups on new Flex-3000
Well, I want to thank everyone for their assistance. It has been a joyride to say the least. The bottom line is that I have abandoned the running of PowerSDR on my laptop, at least for the time being. I will try it again in a month or so. Dudley has spent considerable time on the phone with me trying to work through the issues. Dudley created another thread that is also useful, which is the following: http://www.mail-archive.com/flexradio@flex-radio.biz/msg28441.html So I have done everything that everyone suggested, plus everything Dudley suggested in the thread above to no avail. Without almost nothing else running and even no PowerSDR running, the latency on this laptop still is over 1000uS! Only when I disable the FlexRadio sound driver does it drop to below 300. Obviously, this is not an option. There also seems to be some relationship with the video drivers that is causing an issue also. This laptop has been somewhat problematic since day 1 of its purchase. So I believe that the running of PowerSDR and checking DPC latency has taken the veil off what some of the underlying problems with this laptop are. So I need to get this laptop gone over with some good diagnostic software to find where the problem lies. And as secondary note, I could not get HRD to run with Vcom on it either. More errors and even greater latency. I have brought into service my older 3.0 GHz Pentium 4 (Prescott processor) with only 1 Gb of Ram. It runs PowerSDR with HRD and a number of other programs without any issues. Note that on this machine without an active program running, the DPC latency runs are less than 20uS. With everything running that I would normally use and letting it sit overnight where maintenance routines run, I woke up the next morning to find PowerSDR still running with no problems and max latency seen was about 700 us. When in use and moving lots of things around, latency jumps up to about 400uS under what I would call normal conditions. So it may not be the fastest machine, but it runs without a glitch. So again, thanks to everyone. I may be back on getting the laptop up at a later time. 73, Scott AC8DE -Original Message- From: Neal Campbell [mailto:nealk...@gmail.com] Sent: Friday, May 29, 2009 2:21 AM To: Scott Myers Cc: Tim Ellison; flexradio@flex-radio.biz Subject: Re: [Flexradio] Freeze-ups on new Flex-3000 Scott, I bet that the IRQ sharing with the PSI root port is okay so we can probably discard that.

Re: [Flexradio] Freeze-ups on new Flex-3000
Dave, Thanks for the feedback. Yes, I did disable the root device and of course the Firewire card isn't even seen then. But it was worth a try. I agree that a dedicated machine is ultimately the ticket. And DEFINITELY not a laptop. I would not disable things to the point you did, but the point is taken that having a machine that doesn't have any other garbage riding on it and only the necessary hardware is the right path. But this is not in the financial picture right now. Perhaps in a few months down the road.

A decent computer is so integral to making the flex work well it seems odd that people are so intent on making their current computers do the job. My flex computer only runs the flex and does nothing else. Stripped it back to the basics and it isn't even connected to the internet as I disabled the ethernet ports.

Re: [Flexradio] Freeze-ups on new Flex-3000
The major saving will be to turn off indexing which wakes up periodically and scans your disk for changes (eats up disk and processor). I also recommend changing the Performance tab to be performance oriented versus presentation oriented, and just turn on a few presentation options like smoothed fonts. I turn Aero off also, so my Vista machine looks as close to XP as it can get. Also, and this is where your brains will scream at you, but I have never found any antivirus program that didn't mess up my SDR machine (and I have tried a bunch of them). So I leave them off. Especially anything that does real time protection. Commercial machines (i.e. ones you don't build yourself) comes with a lot of what microsoft calls crapware that can eat away at your processor capacity so delete all of those too (unless you are really using them).

When you bring it up, click on the Views menu and select by connection type menu item. Search the entries for your 1394a card and see what else is being shared on the same interrupt. Usually, high DPC is a result of having the fireware card on the same interrupt as a nigh-usage IRQ (like maybe its sharing its IRQ with the USB controllers, video card, graphic cards, etc.) Let me know what you find.

Watch it carefully and you should see a correlation between a very long duration DPC (or several in a row) with the freeze ups. If you see that, then we know where to start looking for the culprit. http://kc.flex-radio.com/KnowledgebaseArticle50328.aspx -Tim -Original Message- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Scott Myers Sent: Thursday, May 28, 2009 8:08 PM To: flexradio@flex-radio.biz Subject: [Flexradio] Freeze-ups on new Flex-3000 I recently received my new Flex-3000. At first it seemed to be working OK. Then I noted it would freeze up right after I started PowerSDR. So I would stop and restart and it would just run for hours. Then I had a memory issue that was unrelated to PowerSDR and had to update my bios and video driver. Than all those little lock ups started happening often; it would happen as often as every 30 seconds or it might go 5 minutes, but it wouldn't be long. So I followed the instructions on the Knowledge Center and backed the sampling all the way down to 48 KHz, turned buffer to 2048. Little noticeable change. I even tried turning on the expert mode for buffer size and tried various settings. Still no change. I am running on a Dell Inspiron 1720 with a NVIDA GeForce 8400 video card. I am using one of the recommended RICOH ExpressCard firewire cards with TI XIO2200 chipset. I have a Centrino Duo processor 2 GHz, 2 Gb of ram, Windows Vista home premium 32 bit and it get a 3.3 Vista performance index. So I am now at a standstill. I can't carry on a QSO for more than 30 seconds with any certainly of not freezing up. Any ideas?
