Thanks.  This problem was fixed in Q4D29.  Please try with Q4D29?

#12637 didn't recommend that, but it did say that the last known
working version was Q4D24.

If au889 contains anything after Q4D24 then it will automatically
reflash next time it has a power cord attached.  I don't know enough
about au889.

The file should be in the /boot directory, and it contains
two files, the data.img file will have an md5sum matching one of

1f61697d66aef3f29bbc0dd69a2dd4c7  q4d24.rom
0effc8d732e847b1245da3cb0da1ec5e  q4d25.rom
09baa37cb297cacff565f1a4a0a298b2  q4d26.rom
0d518ab0f9dd63cd64035202674f5be7  q4d27.rom
da7189125f1e37f56d6e36f0dbc05aa7  q4d28.rom
7e443310a1d8c92b1a683fc8113fd900  q4d29.rom

The file is provided by an RPM package, so you may find the version
also confirmed by:

	sudo rpm -q olpc-firmware

The download directory for au889 might also have a packages file that
lists an olpc-firmware package version.
