Booting ext2 image from 2GB CF card leads to following error:

Writing same image to the 128MB CF card lets it boot (not without problems but that another problem...). Could you please tell me what to do to enable successfull boot from 2GB CF?

Oops is a segfault in kernel mode, so it's unlikely to be card dependent. With r10546 mounting jffs filesystem fails for me on a 256M CF card, while succeeded on 7.09. Please try with 7.09 to exclude definitively a card failure issue.

OK I'll try. But as I said changing card to 128 MB removes segfault...

Edit 11/03/2008
I've recompiled toolchain and segfault just disappeared; Not investigating this further as I don't have free time to do so... Didn't tried 7.09 as it has no support for ALIX.
