rescue USB/ISO doesn't boot.

[DrDrache]

I'm looking into this more myself, but on 2 systems, both ubuntu 12.04.02 i686
One with the LTS enablement pack (fresh install) and one without
(so kernel 3.5.0-34 and kernel 3.2.0-xxx) when the Bootable image is made, then
attempted to boot from, on the same system, and other systems, you get attached screenshot (do not know how to log)

/etc/rear/local.conf are the same each time
USB :
OUTPUT=USB
BACKUP=NETFS

USB_DEVICE=/dev/sdb

BACKUP_URL=usb:///dev/disk/by-label/REAR-000
ISO:
OUTPUT=ISO
BACKUP=NETFS
BACKUP_URL=nfs:///Ip-addres/mnt/storage/rear/

BUT it works perfect with another system also 12.04.02 i686 with kernel 3.9.2, is there a workaround? (manually switch backup images?)

I did a
$sudo rear -v -d -D mkrescue
and here is the resulting .log

It looks like the kernel has problems while decompressing the initramfs on the USB.

Could you try to unzip it manually and extract it with cpio?

I attempted this with 2048 MB of ram on a ubuntu VM
and 1024 MB as well
also used latest GIT, and stable and snapshots from the OSBP

[dagwieers]

The original ramdisk on your Ubuntu, what kind of compression/filesystem does it use ? (check with the file command on both the compressed initrd as well as the uncompressed initrd).

Are there any kernel boot parameters set on the system that may be needed for booting this kernel/initrd ?

[DrDrache]

nothing but the default ubuntu. no flags were added,
the compressed initrd is gzip compressed and "regular file" uncompressed
as well as the kernel, regular file.

@DrDrache I was expecting a CPIO archive or a filesystem...

@DrDrache does the same problem occur with rear-1.15? I'm not sure what we can do to help you with this? Or is it fine to close this issue? No response within 1 month means "yes"

[gdha]

close the issue with "no feedback received" within 1 month - if needed you may re-open the call [ @DrDrache ]
