Using EC2 chumby starter image on Infocast 8, everything is going fine unpacking linux until dreaded kernel panic. last lines from internal UART are
[    8.108026] sdhci_data_irq: Data Error = -110, intmask = 00100000           
[    8.114383] mmcblk0: retrying using single block read                       
/sbin/init: error while loading shared libraries: libc.so.6: cannot open shared6
[    8.150400] Kernel panic - not syncing: Attempted to kill init!       

Looking at the /sbin directory it turns out that there are about 20 broken symlinks, including init > init.sysvinit
I'm wondering if this has to do with the sd card problem Bunnie posted on his blog.
