Hi All, it’s been a while since I posted here!
I have just finished running through a build of LFS 7.10-systemd and have
rebooted my computer. I am currently getting a kernel panic when the kernel
is booting. According to the messages on the screen (which I can try and
transcribe if anyone needs them), it looks like the kernel cannot locate my
‘/’ partition on the USB hard disk, and tells me that I need to correct my
‘root=’ line in the bootloader configuration to one of the partitions on
the internal HD. It seems like the kernel is not detecting the USB disk at
all.
The only significant deviations I have made from the book is that I am
using Extlinux as my USB bootloader, which is being chainloaded from
Ubuntu’s GRUB2, which is on the internal disk. I also have FORTRAN, D and
Obj-C(++) compiled into GCC (though I can’t imagine this being an issue).
My disks:
--------------------------
# /dev/sda (internal, GRUB2)
# Partition Label FS Notes
/dev/sda1 System Reserved ntfs Windows8 Recovery
/dev/sda2 Windows8 ntfs
/dev/sda3 Extended -
/dev/sda5 - cryptswap Ubuntu’s Swap (host system)
/dev/sda6 Root ext4 Ubuntu’s Root (host system)
/dev/sda7 Home ext4 Ubuntu’s Home (host system)
--------------------------
# /dev/sdb (USB 3.0, Extlinux)
# Partition Label FS Notes
/dev/sdb1 MiraBoot ext2 LFS’s /boot partition
/dev/sdb2 VegaSwap swap LFS’s swap partition
/dev/sdb3 Mira ext4 LFS’s / partition
/dev/sdb4 Extended -
/dev/sdb5 Vega xfs External storage
/dev/sdb6 MiraHome xfs LFS’s /home partition
--------------------------
# /boot/extlinux.conf
UI vesamenu.c32
MENU TITLE Vega Boot Menu
DEFAULT lfs
TIMEOUT 300
LABEL lfs
MENU LABEL ^Mira (LFS-7.10-systemd)
LINUX /vmlinuz-4.9.9-lfs-7.10-systemd
APPEND root=/dev/sdb3 rw
LABEL lfstwo
MENU LABEL Mira (^Second option)
LINUX /vmlinuz-4.9.9-lfs-7.10-systemd
APPEND root=LABEL=Mira rw
# Note that both menu entries point to the same partition – both have the
same result.
--------------------------
Any thoughts? Will I need an initramfs to load the USB drivers, or am I
missing something from the kernel configuration?
Thanks all!
Mark.
