Abstract
Examples described herein include systems and methods for retaining information about bad memory pages across an operating system reboot. An example method includes detecting, by a first instance of an operating system, an error in a memory page of a non-transitory storage medium of a computing device executing the operating system. The operating system can tag the memory page as a bad memory page, indicating that the memory page should not be used by the operating system. The operating system can also store tag information indicating memory pages of the storage medium that are tagged as bad memory pages. The example method can also include receiving an instruction to reboot the operating system, booting a second instance of the operating system, and providing the tag information to the second instance of the operating system. The operating system can use the tag information to avoid using the bad memory pages.
