I booted the image in qemu, initially there were no output on the screen. In fact, the system is very much alive, I broke into the debugger several times, and saw the tar/xz/sh working. More, after some time, I got a login: prompt. I have no idea what to expect from this thing, should it output anything after the kernel finished initializing, and why it sit there for 10 minutes. Try breaking into the debugger and see where it progresses. To do this, you would need to boot with the 'boot -d' command from the loader prompt, then do 'w kbd_break_to_debugger 1', then ctrl-alt-esc when you want to activate the debugger. In the debugger, start with the 'ps' command. >=20 > thanks and best regards, > Marian >=20 > PS.: FWIW, the image I build via mfsbsd is here:=20 > http://mon.kernel32.de/mfsbsd-se-CURRENT-mdpatch.iso > And the hd image used for pxe booting is this one:=20 > http://mon.kernel32.de/FreeBSD-10.0-CURRENT-amd64.hd >=20 > _______________________________________________ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org" --OkP4R/eAVrLNUAwh Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iQIcBAEBAgAGBQJRWzb2AAoJEJDCuSvBvK1Ba8cQAIeKMeMBFtv2xbiX7E3f7hes 053Ip3dMxG7pN0EUdgvasakehD5T/1iBSuDWGXZQFalS/TvT1mG7miMfn46aqAC9 cvomxi995JwB+CHC9XKAyv38GcthYGMvEqWKQns2RudACN0c+MWnT5SsQ3FceqKz XtQhuztaqCA5MH1xZS2v4uEdYy+5sac+AV8LiuFsLXh1hUcVSMtP8x6Rlw6FHtxj S8T9lh+jEMEkZzbIn4Gku+dj3xr0eUjDE+uapQSku1WAMLCU/1teJ8BvT6DqqX6N 7M/YTb5AUBZ1v5T4vdhAtlNoZKKRSE6uttTmTOckQvtlXnBbiMjz0BJZg87/MN16 QqDI9JXiKQQ9jaM+969DVqI+Ea9ukwrmuuhu+1KANBhadUu57w245HOQyDbn6lQE I3i5orarsWuyi9TxSs2PhVmU9B+3h1ef663/9uNvI9pnz124WTtE9MSmrN75BUvU 1OazcoAazBjQynQgPRZjPae1L2EazgVFARdwdW9oVf+XGwo7ZweNW0FGbEUTGBH6 zdpXXg0Ire5ES/LzJPfB6rhcSEsmQfJSWnc12gZ2q4Pbj3dKtyWupTFD593NCUpl FJ9Q8w+tfjFdwreF5XKhVlJGzWI7ELSkhZqTKM0HiWaw4KRTQ2Ff1i54DujiP6/h prYbSdAJOxfQCqug1cqs =qZIV -----END PGP SIGNATURE----- --OkP4R/eAVrLNUAwh--
