Hi!
Is full preemption supposed to work on x86-32 machines?
Because it does not work for me. It crashes early in boot, no messages
make it to console. Similar configuration for x86-64 boots ok.
Maybe you can also tell which version(s) you tried, and in which
configuration(s), and how the crash looked like.
I wanted to know if the configuration is supposed to work at all
before starting heavy debugging. From your reply I assume that it
should work.
We still have at least one 4.4-based 32-bit-only target on RT. But there is
likely more, even though I'm promoting to use at least a 64-bit kernel on 64-bit
capable hw for many years, irrespective of RT.

I tried 4.19.13-rt1-cip1 among others. Crash is early in boot, I can
try some early printing...
Best regards,
Pavel
