Public bug reported: ---Steps to Reproduce--- 1) Using latest daily ISO install 14.04.02 as a Power VM guest. 2) Upgrade the kernel to 3.19 level (3.19.0-18-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-3.19.0-18-generic root=UUID=3ea23bcf-7269-432f-bacc-f82c6cdd774e ro splash quiet fadump=on crashkernel=2G-4G:320M,4G-32G:512M,32G-64G:1024M,64G-128G:2048M,128G-:4096M vt.handoff=7 # cat /sys/kernel/fadump_enabled 1 # cat /sys/kernel/fadump_registered 0 # # dmesg | grep -i Firmware [ 0.000000] Reserved 5120MB of memory at 97279MB for firmware-assisted dump [ 0.000000] firmware_features = 0x00000001c45ffc5f # # cat /boot/config-3.19.0-18-generic | grep -i FA_DUMP CONFIG_FA_DUMP=y # Are there any user space fixes missing which prevents me from configuring firmware assisted dump ? == Comment: #4 - Hari Krishna Bathini <[email protected]> - 2015-06-12 05:28:24 == This patch makes kdump-tools fadump aware so as to switch between kdump & fadump seemlessly based on the dump method enabled (fadump/kdump).
