The bug is perfectly reproducible on a system with such a BIOS (for instance ASROCK 939A785GMH).
With RAID disabled the RAM is free up to about 0x9f800 (displaymem in GRUB and lsmmap in GRUB2), with RAID enabled a reserved area appears at 0x92400 (len 0x0dc00). The bug was mentioned long ago somewhere on the internet also in relation to memtest, but I believe any kernel with bzImage format (which an old file was documenting that it gets loaded in that area) will trigger the problem. -- GRUB fails with certain memory configurations https://bugs.launchpad.net/bugs/638945 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
