Newbie questions

[lanas]

Hi all,

  I'm considering RTAI as a replacement for an existing application
running with a Timesys 2.4.18 kernel.  There are 4 kernel modules and a
few user space tasks.  I've printed some RTAI papers and will read them
more carefully while perhaps I can get some feedback here also.

  The need for the change stems from a poor USB stick support in the
aforementioend kernel.  It could be possible to move forward with the
same company but why not opt for a solution that is vendor independant. 
Or at least try it (hoping that it's possible to use nearly all type sof
USB sticks).

  Development using a 2.6.x kernel will be a new thing, for one.  Is
there, in average, a lot of change from a 2.4.18 kernel module
construction to one that can be used with a recent kernel ?  Especially
using RTAI ?

  Is RTAI/Fusion stable enough to be trusted for continuous use ?

  I've got the latest RTAI live CD and ran some tests.  Is there any
tests in there that actually puts a load on the machine while running
tests ?

  I realize these questions are quite vague.

Thanks for any comments,

Al
