Hi, Ed,
I am using mine u-boot with few fixes, it's not without bugs, but it
probably has less bugs than openmoko's u-boot:
http://wiki.openmoko.org/wiki/U-boot-gena2x
Also i'd suggest to try reducing sd card clock in kernel params (in
u-boot env, glamo_mci.sd_max_clk=15000000).
And do backups. I am just removing sd card and do full dd dump of
contents to hdd, this takes 10 mins, but 100% error-proof, easy, fast
and painless recover. without any problems with partitions or anything
else.
Gennady.
