Hi,
I’m working with inforce6301 (Snapdragon 410(APQ8016)).
I’m using custom linux kernel released by inforce which is based on the following release.
https://releases.linaro.org/96boards/dragonboard410c/linaro/debian/18.01/
I would like to use kdump to collect kernel panic log.
I installed the kdump-tools.
sudo apt-get install kdump-tools
I reserved the memory for crash kernel.
[ 0.000000] crashkernel reserved: 0x00000000afe00000 - 0x00000000bfe00000 (256 MB)
kdump-config is the following.
linaro@linaro-alip:~$ sudo kdump-config show
DUMP_MODE: kdump
USE_KDUMP: 1
KDUMP_SYSCTL: kernel.panic_on_oops=1
KDUMP_COREDIR: /var/crash
crashkernel addr: 0xafe00000
/home/linaro/boot/Image
kdump initrd:
/home/linaro/boot/initrd.img
current state: ready to kdump
kexec command:
/sbin/kexec -p --command-line=“root=/dev/disk/by-partlabel/rootfs rw rootwait rootdelay=5 console=ttyMSM0,115200n8 androidboot.emmc=true androidboot.serialno=c36f945 androidboot.baseband=apq mdss_mdp.panel=0:dsi:0: nr_cpus=1 systemd.unit=kdump-tools.service” --initrd=/home/linaro/boot/initrd.img /home/linaro/boot/Image
Image and initrd.img are the same with first kernel.
Make kernel panic occur by the following command.
sudo sh -c "echo c > /proc/sysrq-trigger"
And I got the following log.
Second kernel (crashdump kernel) is loaded but it fails to mount rootfs.
I’ve been investigating the cause but I’ve not known yet.
rootfs is the part of mmc0 but I think mmc0 driver (sdhci-msm ?) is not loaded.
And I think because dtb is not loaded. So do I need to indicate dtb to kexec ?
But according to the following page, we do not need to indicate --dtb when we use uncompressed Image.
https://www.kernel.org/doc/html/latest/admin-guide/kdump/kdump.html
I tried I indicate --dtb but then second kernel does not work at all.
Please tell me the correct procedure to do kdump.
Thank you.

Gave up waiting for root file system device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/disk/by-partlabel/rootfs does not exist. Dropping to a shell!
