libkse crash and sched ule?

[Morten Rodal]

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?
