Hello,
I have a kernel 2.6.15.6 with
http://download.gna.org/adeos/patches/v2.6/i386/adeos-ipipe-2.6.15-i386-1.2-03.patch
patch. In this configuration, CONFIG_PREEMPT doesn't work any more,
i.e. the kernel is not preempted.
With the kernel without ADEOS patch, it works fine. A test program is
at http://www.bwalle.de/temp/kern-preempt.tar.bz2.
Do you know what's wrong?
Ok, bug confirmed and spotted. It's an x86 specific issue that impacts
Adeos back in the pre-Ipipe times. An updated patch will follow once I
made sure that the fix does not cause any regression, especially on SMP
systems. Thanks for reporting this way, the quality of your testcase
made a real difference to locate the issue rapidly.
