SubjectBug#924794: CONFIG_EFI_VARS_PSTORE_DEFAULT_DISABLE should be set
Message-ID<xCIy5-7nf-5@gated-at.bofh.it>
Package: linux-image-amd64
Version: 4.19+104

CONFIG_EFI_VARS_PSTORE_DEFAULT_DISABLE should be set.
Disables writing various crash info to the UEFI NVRAM by default.

UEFI NVRAM is of limited size and of limited write endurance.
Exceeding those limits may result in bricked motherboards.

Thanks.

Actually not mounting /sys/fs/pstore does not prevent the kernel dump writes.

You need to change the efi_pstore module parameter for that.

Like adding "efi_pstore.pstore_disable=1" to kernel cmdline.

Which is what this bug report suggests to do by default.

Thanks.
