[syslinux] extlinux from syslinux 4.04 failed hard after choosing bzImage.
Hi, Today I replaced grub(1) with syslinux on my laptop, after rebooting to syslinux and selecting kernel I got massive freeze along with colorful output to screen - http://i.imgur.com/lFjFc.jpg I think I tried everything, even doing esc and writing after boot: /bzImage-3.1.0, after enter I had the same freeze with the same screen artefacts. How I installed extlinux: mkdir /boot/extlinux extlinux --install /boot/extlinux cp /usr/share/syslinux/menu.c32 /boot/extlinux/ and the config file /boot/extlinux/extlinux.conf: TIMEOUT 30 UI menu.c32 MENU TITLE Boot Menu MENU COLOR title 1;37;40 MENU COLOR border 30;40 MENU COLOR unsel 37;40 #title Gentoo bzImage-3.1.0 #kernel /bzImage-3.1.0 quiet rootfstype=ext4 luks enc_root=/dev/sda2 lvm root=/dev/mapper/vg-rootfs #initrd /initramfs.cpio.gz LABEL Gentoo bzImage-3.1.0 KERNEL /bzImage-3.1.0 INITRD /initramfs.cpio.gz APPEND quiet rootfstype=ext4 luks enc_root=/dev/sda2 lvm root=/dev/mapper/vg-rootfs LABEL test MENU LABEL asdasd KERNEL /bzImage INITRD /initramfs APPEND root=/dev/md2 softraid I tested extlinux into KVM virtual machine and there everything was ok. After booting livecd and reinstalling grub's mbr I was able boot it just fine - so the kernel image is correct. Any idea what could went wrong? I never saw such issue. -- Piotr.

I never saw such issue.FWIW just builded syslinux from git, reinstalled mbr and extlinux to /boot/extlinux with no luck. Removing UI menu.c32 also changed nothing. -- Piotr.

Couldn't boot kernel 3.1.0 with exactly the same symptoms as you (screen full of weird characters). Fortunately, there's a simple workaround I found here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=647603 Just rename the kernel image to something that doesn't end with zero (e.g. bzImage-3.1) and it will boot just fine. Somehow extlinux chokes on kernel image names with zero in the last place. Strange... -- Tyler
