--DKU6Jbt7q3WqK7+M Content-Type: multipart/mixed; boundary="Nq2Wo0NMKNjxTN9z" Content-Disposition: inline --Nq2Wo0NMKNjxTN9z Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable 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? --=20 Morten Rodal --Nq2Wo0NMKNjxTN9z Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename="crash.3" Content-Transfer-Encoding: quoted-printable Script started on Thu Jul 3 23:12:23 2003 # gdb -k kernel.3 vmcore.3 GNU gdb 5.2.1 (FreeBSD) Copyright 2002 Free Software Foundation, Inc.
