Hi Johnathan, Does the Laptop with intel Core 2 Due run ubuntu 7.04 64bit version (the Ubuntu AMD-64 Version)?

In any case, if anybody uses a laptop with ubuntu and gnuradio, I'd love to know about it, because I need to buy a laptop for some testing. Preferably something on the cheaper side, but not a 8 lbs brick. ... I have successfully run basic GNU Radio flowgraphs with full 32 MB/s USB 2.0 connectivity on a Toshiba Satellite A135-S4527 laptop. You can find them for relatively cheap (around $599 USD) from places like Best Buy when they're on sale. They are not the fastest or best, but seem to do ok. I cleaned off the pre-installed Microsoft Vista and installed Ubunutu Feisty Fawn (7.04) without any problem. Everything worked (including the built-in wireless network adapter) under Ubuntu with the exception of the media card reader, but I didn't spend too much time looking for fixes. The ThinkPad T60 would be great, but if you're really strapped for money, this Toshiba laptop might suffice. Looking for a deal? Find great prices on flights and hotels with Yahoo!

Any ideas? Hi Steven, Looks like I need to loosen up the acceptable margin on this particular test. It tests timer events. The failure is not critical. It expected to receive a message in 0.075 seconds, but got it in 0.093 seconds. I've opened ticket:175 on this.

MM, Gardner, wired clocks... You're going to have to be more specific here. the GMSK block uses MM. Let's take a standard cell phone as example. What are the chances if I had the DSP code of cell phone that I would find MM in there. Is Gardner any better? et cetera...
