First, sorry for double post, I did not know if my email went through
first time (maybe for large config file attached)
Same machine 2.6.33.7.2-rt30 boots fine with Ubuntu and no problem at
all, today I tried the new version with Fedora 15 but it crashes early
in the boot process.
I have attached boot log I get from Qemu which is
the same (apart from the CPU number for example). I also have attached
the patch needed for successful build; V4l example in the
documentation was removed (did not compile with new API), also some
gcc4.6 related issues with anonymous union and superfluous warnings
during build was resolved. The patch is just to have the build so it
is not fully documented.
Please let me know if any further information is needed, if I should
submit the crash to another mailing list, or if I should enable some
option in the config file for more elaborate crash log. Since crash is
very early I could not get a crashdump.
I will be happy to look into the source code too (I am learning), if
you can give me some hint, thanks
dashesy
