Here are some test results (for 2.6.16 linux emulation) at: $ uname -a FreeBSD bsam.ru 7.0-CURRENT FreeBSD 7.0-CURRENT #0: Wed Jan 24 01:58:12 MSK 2007 bsam@bsam.ru:/usr/obj/usr/src/sys/GENERIC i386 ...and linux_base-fc6 (a port from my repository), other port dependencies are from FC4: 1. Just work (sometimes messages about an unimplemented syscall(s) do appear): - print/acroread7 - www/linux-opera - www/linux-firefox - www/linux-flashplugin7 - mail/linux-thunderbird - multimedia/linux-realplayer 2. Works but coredumps when exitting: - net/skype 3. Is not executed (some new... or old libraries are needed): - www/linux-mozilla. Sometimes (not stable result) I get the following LOR.
