I would recommend that this kind of information be organized into a
page in the GNU Radio / OpenBTS wiki so that we can have a real record.
For each report, please include
* the OS distribution and release (Ubunutu 9.04, OS 10.4.14, etc.)
* kernel type (linux/mach/etc) and version
* priority modifiers (rtprio, nice, etc.)
* processor type (core duo, atom, ARM8, etc.)
* L1/L2 cache sizes
* USRP clock type
* OpenBTS release
* specific failure symptoms
Hopefully, given all of this, we can determine some kind of pattern
here, or at least know what configurations to avoid.
