Message-ID: <cfe5f7850903180828k60f844c0l475e328649607e3c@mail.gmail.com> Date: Wed, 18 Mar 2009 10:28:06 -0500 From: Ishaq Khan <ishaq.groups@...il.com> To: linux-kernel@...r.kernel.org Subject: MMC: driver fails to recognize insert-remove SD card after data transfer error 84 Hi, Montavista kernel 2.6.21 on omap2430 I have been trying to fix a problem in the MMC driver on OMAP2430. After rapid insert and remove SD card operation, I see the following error message (caused due to data timeout). After this happens the driver no longer detects insertions/removals.. [ 1013.320000] mmcblk2: error -84 transferring data, sector 7961, nr 8, card status 0x900 followed by bunch of I/O errors [ 1013.330000] end_request: I/O error, dev mmcblk2, sector 7961 [ 1013.330000] end_request: I/O error, dev mmcblk2, sector 7962 [ 1013.330000] end_request: I/O error, dev mmcblk2, sector 7963 [ 1013.330000] end_request: I/O error, dev mmcblk2, sector 7964 [ 1013.330000] end_request: I/O error, dev mmcblk2, sector 7965 [ 1013.330000] end_request: I/O error, dev mmcblk2, sector 7966 [ 1013.330000] end_request: I/O error, dev mmcblk2, sector 7967 [ 1013.330000] end_request: I/O error, dev mmcblk2, sector 7968 I have tried a number of patches that floating around but do no good to fix this problem. Would appreciate if someone could share their views regarding this problem.
