Hi,

i can't get a recent debian kernel to boot on my guruplug server+, so i hope you could help me out. I am running a Debian System on the guru with a ESATA Raid connected where the root filesystem is on. With the old 3.2.35 kernel i installed under squeeze the system boots up as expected. Now i have updated to wheezy and tried to install a brand ne kernel 3.16.0 from backports. At first nothing happend after uBoot. I had to update the uboot to an FDT enabled Vesion (2014.01) and appended a dtb file from http://xilka.com/ to the kernel image. After that i can see the kernel booting - but after a few seconds i get a few error messages and a debug shell:

[   31.489735] dracut Warning: Could not boot.
dracut Warning: [   31.494718] dracut Warning: "/dev/sdc2" does not exist
Could not boot.
dracut Warning: "/dev/sdc2" does not exist

Dropping to debug shell.

at first the message was a liddle bit different, something like "dracut Warning: root attribute not set", changed to >> "/dev/sdc2" does not exist<< when i set root=/dev/sdc2.

In the debug-shell there is no device /dev/sdc* - so i assume that the module for the esata port ist not loaded?

i don't know what to do next?

thanks in advance

I tried a bit more, the module sata_mv is included in the initrd i can load it with modprobe:

[    2.015879] dracut: dracut-7 (wheezy) dracut-

[   18.505771] scsi 0:0:0:0: Direct-Access     ATA      JMB352  RAID-1   n/a  PQ: 0 ANSI: 5

but i don't now why it is not loaded automaticaly? Im not shure, is this "device tree" think the reason, or is the "dracut" software building the initrd the problem?
