I'm trying to debug some issues for which dmesg or even better journal after hang would be great to have (essentially I got hang during suspend). But pstore is empty for whatever reason. What am I doing wrong?
| Code: | % zgrep PSTORE < /proc/config.gz
CONFIG_EFI_VARS_PSTORE=y
# CONFIG_EFI_VARS_PSTORE_DEFAULT_DISABLE is not set
CONFIG_PSTORE=y
CONFIG_PSTORE_CONSOLE=y
CONFIG_PSTORE_PMSG=y
CONFIG_PSTORE_RAM=y
% mount | grep pstore
pstore on /sys/fs/pstore type pstore (rw,nosuid,nodev,noexec,relatime)
% ls /sys/fs/pstore -al
total 0
drwxr-xr-x 2 root root 0 Aug 30 11:18 .
drwxr-xr-x 8 root root 0 Aug 30 11:18 ..
% dmesg| grep -i pstore
[ 1.677649] pstore: Registered efi as persistent store backend
