Since QEMU 2.1, we are allocating more space for ACPI tables, so no space is left after initrd for the BIOS to allocate memory. Besides ACPI tables, there are a few other uses of high memory in SeaBIOS: SMBIOS tables and USB drivers use it in particular. These uses allocate a very small amount of memory. Malloc metadata also lives there. So we need _some_ extra padding there to avoid initrd breakage, but not much. John Snow found a case where RHEL5 was broken by the recent change to ACPI_TABLE_SIZE; in his case 4KB of extra padding are fine, but just to be safe I am adding 32KB, which is roughly the same amount of padding that was left by QEMU 2.0 and earlier. Move initrd to leave some space for the BIOS. Cc: qemu-stable@nongnu.org Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Reported-by: John Snow <jsnow@redhat.com> Signed-off-by: Michael S.
