[Dockstar] rescue system ok, squeeze not booting anymore

Hello everyone,

after an uptime of 137 days I ran into some little problems with my dockstar.

The rescue system still works fine, but everytime I boot with the USB disk attached the system only boots into ubit

root@192.168.192.64's password:
/etc/ubit/images:
/etc/ubit/ubimounts:
/etc/ubit/extramounts:

No valid U-Boot environment exists.
You need to reboot once to let U-Boot set its default environment
before the ethaddr setting can be updated, either directly or
with a cached value.

To cache a value, run:
     ethaddr uu:vv:ww:xx:yy:zz
UBIT v0.6 by peaslaker 2010.11-00125-ga21bcca
ubit0-6:~#

fw_printenv says:

ubit0-6:~# fw_printenv
Warning: Bad CRC, using default environment
bootcmd=bootp; setenv bootargs root=/dev/nfs nfsroot=${serverip}:${rootpath} ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}::off; bootm
bootdelay=5
baudrate=115200

The USB disk is allright, fsck shows no errors; if hot-plugged it is recognized by the rescue system without any problems.

Anyone got an idea how to solve the problem???

Fortunately there's no data lost, but I would like to get my tiny fileserver back to work.


Best Regards,

Dirk

Problem solved:

After re-installing /boot/uImage and /boot/uInitrd the system on the USB disk is up and running.
