I have installed debian on my SheevaPlug. After a few days of working it fails and reboot gives me following:

More likely problem is related to file system overflow caused by my process that writes too much debug output via syslog.
Once I have recovered by
- booting with USB stick,
- mounting Flash partition
- removing log files from /mount/var/log/messages
After that I can boot again from Flash.
But now board is not at my hands and all I can do is to ask customer to enter a commands via RS232 terminal.
My questions are:
- Is where any wayt to recover it with uboot commands only?
- What actually happens? I mean what is problematic in u-boot output above and where actually the problem starts?
Thanks a lot.
