i use 2.6.10-gentoo-r6 kernel and mc-4.6.0-r8. I runnig mc in the console. When I ctrl-o mc goes to console and i can use it. When i ctrl-o again, when mc must go to mc(blue-white interface) system totally hangs (ATX power button stop working, mplayer stop playing). And i must hardware reboot (reset or switching on/off the pc). I did an strace and here end of its output: time(NULL) = 1108298881 time(NULL) = 1108298881 time(NULL) = 1108298881 time(NULL) = 1108298881 time(NULL) = 1108298881 rt_sigaction(SIGTSTP, {SIG_IGN}, {0xb7e7ca60, [], SA_NOMASK}, 8) = 0 ioctl(1, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost -isig -icanon -echo ...}) = 0 ioctl(1, TIOCGWINSZ, {ws_row=48, ws_col=128, ws_xpixel=0, ws_ypixel=0}) = 0 ioctl(1, SNDCTL_TMR_STOP or TCSETSW, {B38400 opost -isig -icanon -echo ...}) = 0 write(1, "\33[1;48r\33[39;49m\33]R\33[0;10m\33[4l\33[3"..., 2800 Here my emerge --info: emerge --info Portage 2.0.50-r8 (default-x86-1.4, gcc-3.3.3, glibc-2.3.3.20040420-r0, 2.6.7) ================================================================= System uname: 2.6.7 i686 AMD Athlon(tm) XP 2000+ Gentoo Base System version 1.5.1 Autoconf: sys-devel/autoconf-2.59-r4 Automake: sys-devel/automake-1.8.5-r1 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CFLAGS="-march=athlon-xp -pipe -O2" CHOST="i686-pc-linux-gnu" COMPILER="gcc3" CONFIG_PROTECT="/etc /usr/X11R6/lib/X11/xkb /usr/kde/2/share/config /usr/kde/3/share/config /usr/lib/mozilla/defaults/pref /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-march=athlon-xp -pipe -O2" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs ccache sandbox" GENTOO_MIRRORS="http://gentoo.oregonstate.edu http://distro.ibiblio.org/pub/Linux/distributions/gentoo" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="3dnow X alsa avi berkdb cdr crypt cups dvd encode esd foomaticdb gdbm gif gpm gtk gtk2 imlib jpeg libg++ libwww mad mikmod mmx motif mozilla mpeg ncurses nls oggvorbis opengl pam pdflib perl png python quicktime readline sdl slang spell sse ssl svga tcpd truetype x86 xml2 xmms xv zlib" Reproducible: Always Steps to Reproduce: 1.run mc in console 2.press ctrl-o 3.press ctrl-o again Actual Results: system totally hangs.

please try vanilla-2.6.10 kernel
i made a mistake in mc version. a use mc-4.6.0-r12 version, not r8
I have try 2.6.10-vanilla and everything works fine.
problems has been solved when i switch off CONFIG_FB_VESA_TNG in the kernl config file.
then it's a kernel thing, so
I have a similar problem with mc in the text console, except that in my case the "offending" action is to hit enter on a file. Then mc either hangs the system immediately (eg. on *.pdf file), or takes a proper action (eg. opens nano on *.tex) and hangs the system on exiting nano. This problem does not appear in X console. I also use CONFIG_FB_VESA_TNG flag in kernel. The last message of strace is also write(1, "\33[1;48r\33[39;49m\33]R\33[0;10m\33[4l\33[3"..., 2800 Should I report this behavior as a separate bug to bugs.gento.org? Or anywhere else? After all, it's not a nice thing to have in your system a very popular program that can easily hang the system!
please report a bug against gentoo-dev-sources
