Doc Text:
A flaw was found in the Linux kernel, related to the initialization of memory blocks reserved on Node#0 at boot time. A kernel panic can be triggered if the DEFERRED_STRUCT_PAGE_INIT feature is enabled, which is caused by a kernel paging request failure at an invalid memory address, which could lead to crashes and unpredictable behavior during boot.
