I updated to the latest sources early today (CEST time) and install
rtld-elf with libmap support in order to give KSE another try.
However upon starting the Mozilla Firebird executable with very simple
/etc/libmap.conf:
libc_r.so.5 libkse.so.1
libc_r.so libkse.so
the computer starts to dump core in the background (I haven't got a
serial cable right here) and then reboots. Apart from stripping all
the devices I haven't got from GENERIC kernel I have added SCHED_ULE.
Is there a know problem with using SCHED_ULE and KSE?
