Hmm, I can't reproduce it here.
grub2 entry is:
menuentry 'Debian GNU/Linux, with Linux 3.10.0+' --class debian --class gnu-linux --class gnu --class os {
load_video
insmod gzio
insmod part_msdos
insmod ext2
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set=root adbbd17b-6e04-4458-814f-9a2b75a4d91e
echo 'Loading Linux 3.10.0+ ...'
linux /boot/vmlinuz-3.10.0+ root=/dev/sda1 ro resume=/dev/sda2 ignore_loglevel
}
Kernel is: v3.10-8587-g496322b
.config settings are:
$ zgrep -E "(INITRD|MICROCODE)" /proc/config.gz
CONFIG_BLK_DEV_INITRD=y
CONFIG_MICROCODE=y
CONFIG_MICROCODE_INTEL=y
CONFIG_MICROCODE_AMD=y
CONFIG_MICROCODE_OLD_INTERFACE=y
CONFIG_MICROCODE_INTEL_LIB=y
CONFIG_MICROCODE_INTEL_EARLY=y
CONFIG_MICROCODE_AMD_EARLY=y
CONFIG_MICROCODE_EARLY=y
# CONFIG_ACPI_INITRD_TABLE_OVERRIDE is not set
Can you send me your .config and your grub entry please?
Thanks.
