Hi
I tried to update the firmware of my Cyclades-TS800.
I followed the instructions to upload the bin file via scp from ftp://ftp.avocent.com/public/product-upgrades/$DS1800/TS/TS_v3.0.0-2b/fl0577002.bin to /proc/flash/zImage
I also checked the md5 of the file and it was correct!
After that I found how I have to restore a bricked devices via network boot and I followed this and now I get a kernel panic, following the output of the serial session (putty):

Any ideas how I can make the device work again? I don't need any settings it can be set to factory defaults!
