------- Additional Comments From Tuukka.Hastrup at iki.fi  2007-09-11 19:35 -------
I have a system on the SD card (ext3 file system, thus valid ext2 too) which I
was able to boot fine with the U-Boot that shipped with my phone (U-Boot
1.2.0-moko9_r8_70124c2602ae2d4c5d3dba05b482d91548242de8_0_2040 (May 19 2007 -
06:59:48)).

U-Boot now crashes when I try to access the SD card, this is after I upgraded
U-Boot to the 2007.8 snapshot version (U-Boot 1.2.0-moko9_r0 (Aug 19 2007 -
19:17:12)) Now I realize the version number is actually lower, did I in effect
downgrade instead of upgrade?

In any case, here is the output of what happens with the 2007.8 snapshot U-Boot:
