[Boot problems with custom kernel]

OK, I must confess, I do have UUIDs in my /etc/fstab, but since I am not on my linux comp at this time, I simply used the /dev/sdXnn nomenclature and for clarity.

 

Said that, /dev/sdXnn should work too, as long as your hardware setup doesn't change and you do not have a misbehaving BIOS, UEFI or the boot script/setup fails to cope with it. I do use /dev/sdXn in VirtualBox at work place and I do not have problems with it.

 

You would likely know if the problem is with using UUID/LABEL or /dev/sdXnn by looking at the boot logs.

 

Oh, btw I have double checked the UUIDs and they are correct.

[Boot problems with custom kernel]

Booted using UEFI, rEFInd boot manager which in turn loads grubx64.efi, then on I manually specify the kernel CL as :

linux /boot/vmlinuz-3.17.2 root=/dev/sdb1 rw

Regardless of the boot method, it results in the same. I suspect that my .config is missing a CONFIG_ option that OpenRC depends on, will need a lof of time and effort to figure that out, unless I turn out lucky !

That was quick, thanks Oleg ! ;-)

 

OK, so the relevant partitions to my setup are as follows:

/dev/sda: 254G SDD -- GPT

/dev/sda1   EFI
/dev/sda2   Win 8.1


/dev/sdb: 4TB SATA III  -- GPT
/dev/sdb1   Funtoo /
/dev/sdb2   NTFS
/dev/sdb3   NTFS
/dev/sdb4   Funtoo Data
/dev/sdb5 NTFS
.
.   
 /dev/sdb10 NTFS

/dev/sdc: 1TB SATA II -- GPT         --> Holds NTFS Partitions

/etc/fstab contents as follows:

/dev/sdb1                  /                     ext4
/dev/sdb4                  /mnt/data       ext4
/mnt/data/vcache      /var/cache     none                   <---[bind mount]
/mnt/data/vdb            /var/db           none                   <---[bind mount]
/mnt/data/uportage    /usr/portage  none                   <---[bind mount]
/mnt/data/usrc           /usr/src         none                   <---[bind mount]
tmpfs                         /tmp               tmpfs   size=20G

I do not use initramfs, I have tried using better-initrams but to no avail.

 

I had saved a copy of .config on my androind, so I have attached it.

 

Hardware used:

Asus maximus V Extreme (Ivy Bridge MB)

CPU - i7 3770K

RAM - 32G  GSkill TridentX @2400MHz

GPU - GTX 660 Ti - 2xSLI

 

Need more info ? Please ask.

[Boot problems with custom kernel]

I've got this problem with a custom compiled kernel, something I never encountered before since my  use of linux since 1994. I am pretty sure I am overlooking something silly !

 

I have spent hours into coming up with that perfect lean kernel with support for my exotic hardware and removing all the unnecessary cruft. If I boot up a generic kernel, I do end up with a working system.

 

Kernel boots up, manages to mount the root filesystem read-only (mounts read-write if specify rw on kernel CL) and then OpenRC init kicks off but fails to mount filesystems from the /etc/fstab file and /dev/pts, /dev/mqueue etc. I am dropped to the login prompt, I can login and mount the filesystems manually, then it segfaults.

 

I have attached a screenshot that shows the OpenRC init sequence leading up to the login prompt. I am pretty sure, I will be asked for /etc/fstab and .config, but I was hoping if someone has encountered this already and know what could be missing from my .config. I am not on my linux comp right now, will have to do that tonight, if needed.

 

 

Thanks for any help.
