 |
|
I am trying to setup pstore, but I am not sure if I am doing this right.
> Parameter printk.always_kmsg_dump writes to pstore at kernel shutdown or reboot.
This should create a file on a regular reboot, but it does not create one.
| Code: | #grep -i pstore .config
CONFIG_PSTORE=y
CONFIG_PSTORE_DEFAULT_KMSG_BYTES=10240
CONFIG_PSTORE_COMPRESS=y
CONFIG_PSTORE_CONSOLE=y
CONFIG_PSTORE_PMSG=y
CONFIG_PSTORE_RAM=y
CONFIG_PSTORE_ZONE=y
CONFIG_PSTORE_BLK=y
CONFIG_PSTORE_BLK_BLKDEV=""
CONFIG_PSTORE_BLK_KMSG_SIZE=128
CONFIG_PSTORE_BLK_MAX_REASON=2
CONFIG_PSTORE_BLK_PMSG_SIZE=128
CONFIG_PSTORE_BLK_CONSOLE_SIZE=128
