Public bug reported:
---Steps to Reproduce---
1) Using latest daily ISO install ubuntu15.10 as a Power VM guest.
2) Upgrade the kernel to 4 level (4.0.0-4-generic)
3) In order to use Firmware Assisted Dump feature update the kernel command
with fadump=on.
4) Reboot.
Post reboot using kdump-config load command fails with following message
:
# kdump-config load
Memory for crashkernel is not reserved
Please reserve memory by passing"crashkernel=X@Y" parameter to kernel
Then try to loading kdump kernel
* failed to load kdump kernel
# kdump-config status
current state : Not ready to kdump
#cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinux-4.0.0-4-generic
root=UUID=6298dfdc-e683-473d-a8bc-b3249731b356 ro splash quiet fadump=on
fadump_reserve_mem=512M crashkernel=512M
#cat /sys/kernel/fadump_enabled
1
#cat /sys/kernel/fadump_registered
0
# dmesg | grep -i Firmware
[ 0.000000] Reserved 512MB of memory at 3583MB for firmware-assisted dump
[ 0.000000] firmware_features = 0x00000001c45ffc5f
#cat /boot/config-4.0.0-4-generic | grep -i FA_DUMP
CONFIG_FA_DUMP=y
I think userspace tool is missing for fadump as kdump config file not aware
about fadump
