Ah really... that sounds more like generic Glamo-trashing than
MCI-specific issue.  All the SD stuff goes through the Glamo so maybe
it's just pointing at something deeper that's not directly to do with SD.

GPRS uses more slots AIUI so it dents the battery more during TX, maybe
the issue is around that.  Eg, dodgy Glamo reset circuit.

What would help is dump the glamo regs while it's normal, and if you see
that trashed display again, dump it if possible and we can see the diff.

Thanks, maybe we can get a clue.
