Just to let you know, this doesn't work on a fresh install of natty beta 2.

Edit: It also doesn't work after upgrading from maverick.

According to the bug report, to make the fix persist across reboots, you need to "sudo update-initramfs -u". This works on my Toshiba X505-Q893 under 64-bit 10.04. Curiously in 32-bit Ubuntu 8.04, the SD card reader worked fine without any tweaking.

Here's the whole setup, if you just want to copy-and-paste:

sudo su

cat > /etc/modprobe.d/toshiba_sd_reader.conf << EOF
# Disable ADMA to workaround a sequence of errors which looks like:
#    mmc0: Unexpected interrupt 0x02000000.
#     mmc0: error -110 whilst initialising SD card
# when an SD card is inserted to the card reader on a Toshiba X505
# See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/605043
# or http://ubuntuforums.org/showthread.php?t=1544350

options sdhci debug_quirks=0x40
EOF

rmmod sdhci_pci sdhci
modprobe sdhci
modprobe sdhci_pci
update-initramfs -u

exit

I know this is an oldish thread but I wanted to say this solution worked for me.

I am running Mint 12 on a Qosmio x500 (18.4 inch screen - wooo!)

The SD card is a 32G SDHC from my Canon T3.


Figured someone might be in a similar situation as I.

Thanks a lot for this solution. It's much appreciated.
