As a usual I used a CDMA modem to connect to Internet. I have an instance of kernel, that "goes into panic" if I run vwdial. Wvdial I run via bash script: [code] #! /bin/sh route del -net 0.0.0.0 vnstat --enable -i ppp0 wvdial [/code] With same kernel config (attached) I tried to do same in vanilla kernel (2.6.27.19) and all run smoothly. Once I saw a big stacktrace after this bug, but I could not "save" it Reproducible: Always Steps to Reproduce: 1. log in 2. become a root (via "su -") 3. run wvdial Actual Results: In few seconds system does not react on my actions, capslock LED blinks. I sure I get "kernel panic" bug Expected Results: Connection should be established, and WWW should be accessible Kernel: sys-kernel/gentoo-sources-2.6.27-r8 wvstreams: sys-kernet-libs/wvstreams-4.4 wvdial: net-dialup/wvdial-1.60 emerge info: Portage 2.1.6.7 (default/linux/x86/2008.0, gcc-4.1.2, glibc-2.6.1-r0, 2.6.27-gentoo-r8 i686) ================================================================= System uname: Linux-2.6.27-gentoo-r8-i686-Intel-R-_Core-TM-2_CPU_T5600_@_1.83GHz-with-glibc2.0 Timestamp of tree: Mon, 09 Mar 2009 16:15:12 +0000 distcc 2.18.3 i686-pc-linux-gnu (protocols 1 and 2) (default port 3632) [enabled] app-shells/bash: 3.2_p39 dev-java/java-config: 1.3.7-r1, 2.1.6-r1 dev-lang/python: 2.5.2-r7 dev-python/pycrypto: 2.0.1-r6 dev-util/cmake: 2.6.2-r1 sys-apps/baselayout: 1.12.11.1 sys-apps/sandbox: 1.2.18.1-r2 sys-devel/autoconf: 2.13, 2.61-r2 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10.2 sys-devel/binutils: 2.18-r3 sys-devel/gcc-config: 1.4.0-r4 sys-devel/libtool: 1.5.26 virtual/os-headers: 2.6.27-r2 ACCEPT_KEYWORDS="x86" ALSA_CARDS="hda-intel" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" ANT_HOME="/usr/share/ant" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias proxy" ARCH="x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CCACHE_SIZE="1G" CFLAGS="-march=prescott -O2 -pipe -fomit-frame-pointer" CHOST="i686-pc-linux-gnu" CLASSPATH="."

Created attachment 185617 [details] kernel config
The only thing mentioned in this bug that is maintained by net-dialup is wvdial. Since user space cannot produce kernel crashes, I see no point in assigning this bug to wvdial maintainers. Reassigned to kernel team.
Can you please test with gentoo-sources-2.6.27-r10 when it hits the mirrors.
With ~linux-2.6.27-gentoo-r10 all works OK
Thanks for testing
