Comment 1 Andrew Morton 2011-07-11 20:16:20 UTC
From which kernel version is this a regression? Was 2.6.39 OK?
Comment 2 Peter Vollmer 2011-07-11 20:58:36 UTC
It is a regression of the 3.0.0-rc6-mainline Kernel. With the current Kernel 2.6.39 of Arch Linux I've had no Problems.
Comment 3 Chris Ball 2011-07-11 21:21:23 UTC
Thanks for the report. Does reverting the below commit help? It added some PCI quirks for your chip, and was merged in 3.0-rc5: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=be98ca652faa6468916a9b7608befff215a8ca70 If it doesn't help, I can't think of anything else obvious -- it would be great if you could try a bisect between 2.6.39 final and 3.0-rc6.
Comment 4 Chris Ball 2011-07-11 21:23:16 UTC
Oh, yeah -- you could also just disable CONFIG_MMC_RICOH_MMC, assuming it is currently =y on your system. Does that help?

Comment 6 Peter Vollmer 2011-07-15 19:06:22 UTC
Hi Chris, first of all thanks for your help. I'm finish with some of your tips: The tip of comment #4 doesen't work. I've got the error message that the config wasn't able to load. Also the cardreader doesn't work. The other thing I've done was the bisection thing. The result is this commit: a3c7778f8153b9e4eceea6738973280b9e63c618 is the first bad commit commit a3c7778f8153b9e4eceea6738973280b9e63c618 Author: Andrei Warkentin <firstname.lastname@example.org> Date: Mon Apr 11 16:13:42 2011 -0500 mmc: sdhci: R1B command handling + MMC_CAP_ERASE. ERASE command needs R1B response, so fix R1B-type command handling for SDHCI controller. For non-DAT commands using a busy response, the cmd->cmd_timeout_ms (in ms) field is used for timeout calculations. Based on patch by Chuanxiao Dong <email@example.com> Signed-off-by: Andrei Warkentin <firstname.lastname@example.org> Signed-off-by: Chris Ball <email@example.com> :040000 040000 900ad3058ed393172ff7e68a2240a5404c28bfbb bb4a8b4bd336b0a53b8f90ebc37d16929e5ccfd4 M drivers I hope I can help to resolve this problem.

Comment 8 Chris Ball 2011-08-09 11:09:11 UTC
Hi Peter, Please could you retry with 3.1-rc1? We've added a patch to slow down the MMC clock rate on your chipset, which has fixed IO errors on other machines.
Comment 9 Chris Ball 2011-08-09 19:11:02 UTC
.. and if you want to try applying the patch separately, it is: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=15bed0f2fa8e1d7db201692532c210a7823d2d21
Comment 11 Peter Vollmer 2011-08-10 10:23:52 UTC
Hi Chris, On Kernel 3.1-rc1 the reader doesn't work at all. See the attached log for details.
Comment 12 Peter Vollmer 2011-08-12 08:16:37 UTC
Created attachment 68662 [details] kernelpanic after login Hi Chris, now I've got another kernelpanic from the cardreader, but today it was directly after login. A card was in the readed and it tried to mount it I think. I was the first time. Peter
Comment 13 Peter Vollmer 2011-08-12 08:19:06 UTC
I'm using the kernel 3.0-Arch.

Bug #42568 - ThinkPad T520 I/O errors during accessing SD card with internal reader https://bugzilla.kernel.org/show_bug.cgi?id=42568 might be related, but I think I had this with 2.6.39 as well. I am not completely sure tough, since I didn´t note kernel version of older saved log excerpts.
Comment 16 Alan 2013-12-23 14:06:02 UTC
If this is still present in modern kernels please update the bug
