That's a kernel line from a GRUB entry I think. GRUB reads it to find a
bootable linux image and also contains the parameters that get passed
from GRUB (the bootloader) to linux. the first parameter /bzImage is
the name of the linux kernel image file and should correspond to an
actual file in your /boot directory. Remeber that "/vmlinuz not found"
error? It looks like your distro uses the name bzImage instead. If you
press and release the key 'e' when an entry is selected in GRUB you
will be able to temporarily change "/vmlinuz" to "/bzImage" or anything
else. Making small changes that way is another easy and failsafe method
to troubleshoot your boot problems.
Loglevel is fine, it just controls the verbosity of linux's error and
warning reporting. To be honest I don't know why sshd is mentioned. I
don't even think that's a valid kernel parameter, but kernel parameters
are unrelated to boot failures. It is the /bzImage thing and possibly
the root partition that we need to get right in order to make
Libreboot's GRUB find and boot your operating system.
Did you try copying grub.cfg into libreboot_grub.cfg?

Can you tell me what the command below does? It looks as if it
enables sshd on the root partition (sda2) correct, or no?
linux /bzImage croot=/dev/sda2 sshd loglevel=2

Hi Isaac,
My technical knowledge of Linux is limited to basic command line
stuff. I'm not sure I would be able to get this working, I don't
think.
I emailed the developer of the OS I am using and told him about the
issue, below is his response. Maybe a place to start, not sure of
the answer to his last two questions:
"Libreboot has its own bootloaders. This can be Seabios or grub in
most
cases. Seabios is the best for FL, but the one you are using now
looks
like grub. Do you know which options are enabled in the BIOS for
booting
the system? Is it possible to set them without recompiling the
BIOS?"

I can offer my help as a Libreboot user. That last grub entry
"search for grub configuration outside..." should be working. It
may be the case that your distro gives a different name to the
linux image under /boot.
Could you troubleshoot from a live USB and use this guide to
create the file /boot/grub/libreboot_grub.cfg using a working grub
configuration?

I bought a Lenovo T400 with Libreboot installed and I am able to
boot from USB, but when I try to
boot the Linux operating system I installed I get error: file
'/vmlinuz' not found. I tried booting the
last option on the grubscreen list which is 'search for grub
configuration outside..' but that did not
work and resulted in the same error.
Looking for some help with getting the OS booted up.
Indeed, instead of loading the bootloader installed by the operating
system in your hard drive, Libreboot uses its own GRUB payload which
gets flashed into the chipset alongside Libreboot itself.
The first method from the Libreboot guide I sent to you doesn't
require any skill other than moving around in the file manager. We
could skip the command line altogether. I can't guarantee it will
work but the whole endeavour is failsafe; your firmware, operating
system and files will stay untouched no matter what happens. This is
why I think it's worth trying. It's up to you Shawn.
In summary: boot from the USB stick, find the /boot directory
somewhere in your hardrive volumes (it should be at the root level
of your GNU/Linux file system or be its own partition, in which case
you'll be able to identify it because it will contain linux images
and hopefully a folder called "grub"). Assuming there's a grub
directory in there, dive in and copy the file grub.cfg into the same
directory and give it the name libreboot_grub.cfg. This file
grub.cfg is automatically generated in most GNU/Linux distros
whenever the kernel is installed or updated, and it is likely to
contain the configuration needed to get from GRUB to the operating
system. Then just reboot and test. Libreboot's GRUB is supposed to
search your hardrive partitions for the libreboot_grub.cfg file and
load its configuration.
Tell us how it goes.
