When I run the program vbetool (which I need to properly suspend my laptop to ram), I get the error "mmap /dev/mem: Permission denied". Also it leaves a message in dmesg that says "program vbetool is using MAP_PRIVATE, PROT_WRITE mmap of VM_RESERVED memory, which is deprecated. Please report this to linux-kernel@vger.kernel.org". I think the problem is that I am using the mm-sources (my root is reiser4, so I can't test with other sources in portage). I have tested this on 2.6.14-rc5-mm1 through 2.6.14-mm2 with the same results. I have also tried many configs, and I modified the vbetool code so it doesnt leave the error in dmesg, but the results are the same. I got the same results for vbetool 0.2 and 0.3 (the only ebuilds in portage for vbetool) Reproducible: Always Steps to Reproduce: (as root) 1. emerge vbetool 2. vbetool 3. hibernate Actual Results: mmap /dev/mem: Permission denied is printed to the screen. If I try to run the hibernate script, the screen flickers a bit, and then aborts because the vbetool command fails. Expected Results: suspend to ram All my configs (including emerge info) can be found at http://web.pdx.edu/~piercede/configs/ Gentoo Base System version 1.12.0_pre10 Portage 2.0.53_rc7 (default-linux/x86/2005.1, gcc-3.4.4, glibc-2.3.5-r3, 2.6.14-mm2 i686) ================================================================= System uname: 2.6.14-mm2 i686 Intel(R) Pentium(R) M processor 2.00GHz dev-lang/python: 2.3.5-r2, 2.4.2 sys-apps/sandbox: 1.2.13 sys-devel/autoconf: 2.13, 2.59-r7 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r1 sys-devel/binutils: 2.16.1 sys-devel/libtool: 1.5.20-r1 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=pentium4" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.4/env /usr/kde/3.4/share/config /usr/kde/3.4/shutdown /usr/kde/3/share/config /usr/lib/X11/xkb /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/texmf/web2c /etc/env.d" CXXFLAGS="-O2 -march=pentium4" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks sandbox sfperms strict" GENTOO_MIRRORS="http://gentoo.osuosl.org/ http://gentoo.mirrors.easynews.com/linux/gentoo/ http://cudlug.cudenver.edu/gentoo/" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 X alsa apache2 apm arts audiofile avi berkdb bitmap-fonts bzip2 crypt cups dts eds emboss encode esd ethereal expat fam foomaticdb fortran gd gdbm gif glut gmp gnome gpm gstreamer gtk gtk2 guile idn imagemagick imap imlib ipv6 java jpeg kde lcms libg++ libwww mad mikmod mmx mng motif mp3 mpeg mysql ncurses nls ogg oggvorbis opengl oss pam pcre pdflib perl php png python qt quicktime readline sdl spell sse sse2 ssl tcpd tetex tiff truetype truetype-fonts type1-fonts udev usb vorbis xml2 xmms xv zlib userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, LANG, LC_ALL, LDFLAGS, LINGUAS, MAKEOPTS, PORTDIR_OVERLAY
(In reply to comment #0) > I think the problem is that I am using the mm-sources Looks pretty much like that - http://comments.gmane.org/gmane.linux.kernel/345779 Anyway, mm-sources is not a supported kernel - see http://www.gentoo.org/doc/en/gentoo-kernel.xml#doc_chap3 Feel free to reopen if you are able to reproduce the problem with a supported kernel or if you have a sane patch. Thanks.
Could someone reopen this, as i am able to reproduce it with 2.6.15-rc1.
