-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm running on x86: Debian Wheeze with the preempt-rt patches and a stock Debian preempt-rt kernel:
charles@deb:~$ uname -a Linux deb 3.2.0-3-rt-686-pae #1 SMP PREEMPT RT Mon Jul 23 05:49:20 UTC 2012 i686 GNU/Linux I'm not sure if the -fPIC has anything to do with the problem or not, just that it happened somewhere between the two commits I mentioned and that I spent more time than I should have thinking my code I'm writing to interface to my 3D printer was broken. I don't have time to bisect the issue now, but I'll try to see if I can figure out what's wrong in the next day or two. ...back a bit more on topic, I'd like to see the preempt-rt patches integrated into the mainline code. There are some obvious issue that need fixing before this can happen (ie: at least the packaging scripts need to be updated so a *.deb can be built). Otherwise, what would have to happen for the inclusion of a preempt-rt option to be considered?
