I did the echo 1 > /sys/module/glamo_mci/parameters/sd_idleclk
and I am now able to suspend/resume (tried with Qtopia booted from SD 8GB)
Before that it always failed (tried with qtopia / 2007/02 / 2008/8
...), with often lost partion table.
Will be ok if we can have a script on suspend/resume, or maybe if the
kernel modification on sd_idleclk was patched to better handle on
suspend...
why was the "dd if=/dev/mmcblk0 of=/dev/null count=1" for ? I
didn't do that.... (I had partition table saved to disk before trying
but I think I rebooted after)
Thanks a lot ! I finally can use my 8gb card... (well.. I hope it will
continue to work)
