update: 24 April 2009 17h10 MEZ SD CARD problem_test precisions
I noticed that suddenly a SD card auto-mounted as with U8.10. So I tested 4 SD cards
all of which worked with no problems on U8.10.
ADATA 16GB SDHC
Extreme Memory 2GB SD
TOPRAM 16GB SDHC
Transcend 16GB SDHC all work fine with U8.10
Running U9.04
ADATA 16GB SDHC does not work, but will work OK when used with a USB adapter
.
Extreme Memory 2GB SD does not work, but will work OK when used with a USB adapter
TOPRAM 16GB SDHC works fine.
Transcend 16GB SDHC works fine.
Summary: ADATA 16GB SDHC + Extreme Memory 2GB SD no longer work
with U9.04, but worked fine with U8.10 in the SD Card slot in the DELL Mini-9.
----------
update: this is not so much a problem with disk mounting, but with broken support to recognize or to initialize SD cards. The 2.6.28-11-generic kernel can no longer initialize SD cards. Computer used is a DELL Mini-9.
After distribution upgrade from 8.10 to 9.04, the disk mounter is no longer present in the Panel and can not be added. Inserting a SD-card into a DELL Mini-9 goes unrecognized, before with 8.10 I saw the SD card in the panel and could dismount it and remount it. Also a SD card icon appeared on the desktop, in Places, and in File Manager. Now nothing.
This is a real show stopper.
A few minutes ago, I did an update and upgrade, but it didn't show any effect for the auto-mount of the SD card. Disk mounting has disappeared from 9.04 GUI
lspci shows SD Host Controller present.
uname shows 2.6.28-11-generic #42 Ubuntu SMP
dmesg shows: mmc0: error -84 whilst intialising SD card
tried both 16GB SDHC and 2GB SD that worked yesterday with 8.10, both show
mmc0: error -84 whilst intialising SD card
Pressing ESC key at bootup and choosing 2.6.27-11-generic shows that
1- disk mounter works as before in 8.10, but
2- CPU frequency-scaling is broken, error msg appears saying this is not supported and the Atom processor stays at full-speed of 1.6 GHz and will not drop down to the usual 900 MHz.
Therefore after upgrade from 8.10 to 9.04, using the 2.6.27-11-generic kernel is no longer an option. This has nasty consequences for tens of millions of Atom CPUs should one need to return to kernel 2.6.27-11-generic in case of a problem. The upgrade to 9.04 breaks the 2.6.27-11-generic kernel.
The freq-scaling bug about breaking the old kernel by the upgrade to 9.04 has been separated and is now at https:/
since it has nothing to do with breaking support for SD cards.

I have had the same problem using a 16GB adata SD card on an aspire one. I did a clean install of 9.04 and it doesn't recognise the SD card. If I boot off the 8.10 live cd, it is detected and works perfectly.
