Title:
  Ricoh R5C822 SDHC Card reader I/O errors

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  (replies indicate that this problem wasn't specific to SDHC, more like
  specific to this Ricoh reader.  updating description and tags...
  Also, 2.6.27-10 maybe have solved it.)

  Greetings.

  I've recently bought a 4GB SDHC memory card from Adata (class 6) to
  try it out on my Acer Aspire 5920G laptop, running Ubuntu Hardy and
  Windows XP. It has one of those 5-in-1 card readers (SD™, MMC, MS, MS
  PRO, xD) that you get to see in a number of Acer laptops today.
  Unfortunately I wasn't able to make use of the card because a the
  system threw a briefcase full of errors back at me. I found out that
  just by inserting the card into the card slot already generates a
  bunch of errors as seen by dmesg:

  etc...

  Actually the first time I noticed the problem was when I attempted to copy roughly 800 MB of files over to the card in nautilus. This was the first time I ever used a SDHC card or the card reader. The progress came to about 200 MB and then stopped with an error: Error writing to file: Input/output error
  Looking at syslog/dmesg, I could see hundreds more of those i/o errors, including a few of these entries:

  At first I believed it was a faulty SDHC card, but a colleague of mine
  tested the card on his Vista laptop without any problems. I've tried
  formatting the card several times in GParted with a number of file
  systems including fat-16, fat-32 and ext3 of which all failed to work
  properly. Ironically, sometimes even GParted failed to recognize its
  newely created ext3 partition and instead listed it as unknown. Doing
  fsck on the card is another book with 5000 pages.

  Of course I tried to use the card on my other operating system,
  Windows XP, which surprisingly didn't even recogize the card. This
  gave me a reason to believe that my card reader was faulty. I later
  ruled that option out after installing a patch from microsoft
  (WindowsXP-KB934428-v3-x86-ENU.exe), allowing Windows XP to recognize
  4GB SDHC cards and above. Now my card reader was able to work on WinXP
  (same card reader) without any problems. So I do believe I have traced
  the problem back to Ubuntu linux.

  Since the problem happens in Hardy with the latest updates applied, I am therefore reporting this as a bug. I am not sure how to fix this myself, but please let me know when a fix is available.
  Thanks.
