 [ I don't seem to have permission to reopen this bug, could somebody with
 sufficient permissions do it? ]

 Re #2135 I was investigating different ways to save kernel panic
 messages so that they can be retrieved later and thought I should try
 kdump which uses kexec only to notice that kexec does not quite work:

 With stable-tracking at 1b17c67794364bee I built kexec-tools from the
 debian source package 20080324-2 and tried

 {{{
 sudo kexec -l /boot/uImage2.bin --append="`cat /proc/cmdline`"
 sudo kexec -e
 }}}

 but got only WSOD. The device also did not show up as usb device or
 blink any leds.


 My /proc/cmdline contains
 {{{
 rootfstype=jffs2 root=/dev/mtdblock6 console=ttySAC2,115200 console=tty0
 loglevel=8 regular_boot mtdparts=physmap-
 flash:-(nor);neo1973-nand:0x00040000(u-boot),0x00040000(u-boot_env),0x00800000(kernel),0x000a0000(splash),0x00040000(factory),0x0f6a0000(rootfs)
 rootfstype=ext2 root=/dev/mmcblk0p2 rootdelay=5
 }}}
 in case it matters.
