I have now the a bit similar new problem with a non-working SD card
some time after I switched to testing repositories.
The SD card still works in a card reader, but gives in Neo (from dmesg):
mmc0: new high speed SDHC card at address b360
mmcblk0: mmc0:b360 USD 7070656KiB
mmcblk0:<6>glamo-mci glamo-mci.0: Error after cmd: 0x8310
mmcblk0: error -110 sending read/write command
end_request: I/O error, dev mmcblk0, sector 0
(continues with similar I/O errors for some time)
The card is brand new and used to work for a week or so, but then I
noticed the problem yesterday evening when I tried to actually use the
SD card (openstreetmap content) after some while. And like I said, it
still works outside Neo without any problems.
I'm using 2007.2 software, Neo from the first July batch with no
hardware fixes applied.
> echo 1 > /sys/module/glamo_mci/parameters/sd_idleclk
This didn't help.
This did help, I followed instructions at
How is it possible that a previously working card suddenly becomes
non-working without the max clk, I wonder?
