Core 2 - PANIC

Recieved journal commit failure running 2.6.6-1.381 System now fails to boot "mkrootdev: label / not found". Can get further into the boot process using "kernel /vmlinuz-2.6.6-1.381 ro root=/dev/hda5 rhgb quiet" but this only gets me to : EXT3-fs: hda7: couldn't mount because of unsupported optional features (1000100)." <- not sure what they might be. mount: error 22 mounting ext3 I have been trying to get into rescue mode via network (ftp/nfs) but anaconda responds with: ====== Running anaconda, the Fedora Core rescue mode - please wait... File "/usr/bin/anaconda", line 913 xsetup_failed = xserver.startXServer(videohw, monitorhw, mousehw, kbd, ^ IndentationError: unindent does not match any other indentation level install exited abnormally ======= Is their a way I can get this system back to get a better look at logs etc. Where should I be looking for recovery doco etc. Cheers in advance Rodney
