Hey guys, this is bad :( After updating to alsa-1.0.9_rc2, artsd stopped working giving me a segmentation fault, after playing around with artsd options I took a look at dmesg and found this: nel NULL pointer dereference at virtual address 00000000 printing eip: c01e5583 *pde = 00000000 Oops: 0002 [#1] PREEMPT Modules linked in: it87 i2c_sensor i2c_isa joydev usbhid usbmouse ohci_hcd i2c_sis96x i2c_core sis_agp agpgart evdev snd_pcm_oss snd_mixer_oss snd_seq_oss snd_seq_midi_event snd_seq snd_cmipci snd_pcm snd_page_alloc snd_opl3_lib snd_timer snd_hwdep snd_mpu401_uart snd_rawmidi snd_seq_device snd usbcore ntfs vfat fat CPU: 0 EIP: 0060:[<c01e5583>] Not tainted VLI EFLAGS: 00210212 (2.6.11-gentoo-r5) EIP is at memcpy+0x23/0x60 eax: 00000010 ebx: efc858e0 ecx: 00000004 edx: 00000000 esi: ed5cdecc edi: 00000000 ebp: bfffe690 esp: ed5cde94 ds: 007b es: 007b ss: 0068 Process artsd (pid: 10995, threadinfo=ed5cc000 task=ef6fea80) Stack: 00000003 efc85b60 ffffffea ffffffea ed5cdedc f10b6efd 00000000 ed5cdecc 00000010 efc858e0 f10b7d56 efc858e0 ed5cdecc 00000050 00000006 00000000 00000000 00000000 00000005 00000001 00000000 00000000 00008002 00000000 Call Trace: [<f10b6efd>] snd_timer_user_append_to_tqueue+0x3d/0x50 [snd_timer] [<f10b7d56>] snd_timer_user_params+0x236/0x250 [snd_timer] [<f10b8010>] snd_timer_user_ioctl+0x150/0x270 [snd_timer] [<c016a7a0>] do_ioctl+0x70/0xb0 [<c016a9e5>] vfs_ioctl+0x65/0x200 [<c016abc5>] sys_ioctl+0x45/0x70 [<c01031d9>] sysenter_past_esp+0x52/0x75 Code: ff ff c3 90 90 90 90 90 83 ec 14 8b 44 24 20 89 74 24 0c 89 7c 24 10 8b 74 24 1c 3d ff 01 00 00 77 26 89 c1 8b 7c 24 18 c1 e9 02 <f3> a5 a8 02 74 02 66 a5 a8 01 74 01 a4 8b 44 24 18 8b 74 24 0c Am I the only one with this problem? emerge --info: Portage 2.0.51.19 (default-linux/x86/2005.0, gcc-3.4.3-20050110, glibc-2.3.4.20050125-r1, 2.6.11-gentoo-r5 i686) ================================================================= System uname: 2.6.11-gentoo-r5 i686 AMD Athlon(TM) XP 1800+ Gentoo Base System version 1.6.10 Python: dev-lang/python-2.3.5 [2.3.5 (#1, Feb 18 2005, 09:45:38)] distcc 2.18.3 i686-pc-linux-gnu (protocols 1 and 2) (default port 3632) [disabled] ccache version 2.4 [enabled] dev-lang/python: 2.3.5 sys-devel/autoconf: 2.59-r6, 2.13 sys-devel/automake: 1.7.9-r1, 1.8.5-r3, 1.5, 1.4_p6, 1.6.3, 1.9.5 sys-devel/binutils: 2.15.92.0.2-r7 sys-devel/libtool: 1.5.14 virtual/os-headers: 2.6.8.1-r4 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CFLAGS="-march=athlon-xp -O2 -pipe -mmmx -m3dnow -msse -mfpmath=sse -fomit-frame-pointer -fforce-addr -frerun-loop-opt -frerun-cse-after-loop -falign-functions=4" 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/env.d" CXXFLAGS="-march=athlon-xp -O2 -pipe -mmmx -m3dnow -msse -mfpmath=sse -fomit-frame-pointer -fforce-addr -frerun-loop-opt -frerun-cse-after-loop -falign-functions=4" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs autoconfig ccache distlocks fixpackages sandbox sfperms" GENTOO_MIRRORS="ftp://ftp.las.ic.unicamp.br/pub/gentoo http://gentoo.osuosl.org http://www.ibiblio.org/pub/Linux/distributions/gentoo" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 3dnow 3dnowex X aac aalib alsa apache2 apm arts avi bash-completion berkdb bitmap-fonts cdparanoia cdr crypt cscope cups curl dga dvd dvdr emboss encode fam fbcon flac foomaticdb gdbm gif gphoto2 gpm gstreamer gtk gtk2 imagemagick imlib java jpeg kde kdeenablefinal libg++ libwww mad mmx mmxext motif moznocompose moznoirc moznomail mp3 mpeg ncurses nls nptl nvidia oggvorbis opengl pam pda pdflib perl pic png ppds python qt quicktime readline real rtc samba sdl slang speex spell sse ssl tcltk tcpd theora threads tiff truetype truetype-fonts type1-fonts usb xanim xine xml xml2 xmms xv xvid xvmc zlib" Unset: ASFLAGS, CBUILD, CTARGET, LANG, LC_ALL, LDFLAGS Hope this helps.

Dupe of bug #87544. It's not kde-related.
*** This bug has been marked as a duplicate of 87544 ***
Please be specific when reporting alsa bugs. What version of the drivers are you using? What version of alsa-lib? When you say 'alsa-<version>', that's ambiguous. Is this caused when BOTH are updated? Just the lib? Please state this info in bug #87544. Thanks.
