Description of problem: When a SDHC card (which works fine on other systems) is inserted, it is not mounted at all. dmesg provides a bunch of output (here is a snippet): [ 782.874127] end_request: I/O error, dev mmcblk0, sector 0 [ 782.874212] mmcblk0: error -110 sending status command [ 782.874217] mmcblk0: error -110 sending read/write command, response 0x0, card status 0x0 [ 782.874223] end_request: I/O error, dev mmcblk0, sector 1 [ 782.874309] mmcblk0: error -110 sending status command [ 782.874315] mmcblk0: error -110 sending read/write command, response 0x0, card status 0x0 [ 782.874347] end_request: I/O error, dev mmcblk0, sector 2 [ 782.874443] mmcblk0: error -110 sending status command [ 782.874450] mmcblk0: error -110 sending read/write command, response 0x0, card status 0x0 And more of the same. This is on Thinkpad X220, but the offending hardware appears in a handful of other laptops. $ lspci <SNIP> 0d:00.0 System peripheral: Ricoh Co Ltd Device e823 (rev 07) .... Version-Release number of selected component (if applicable): kernel-2.6.40-4.fc15.x86_64 (This was also happening on 2.6.38 before I updated) How reproducible: Insert SD card into internal cardreader. Actual results: Bunch of dmesg errors and no device turns up. Expected results: card filesystems mounted, or device accessible at least somehow. Additional info: When I was trying to figure out what was happening, I discovered that this has been reported (and fixed!!! happytime!!) at ubuntu: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/773524 I can confirm that the workaround in the comments works for me. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/773524/comments/13 I haven't gone so far as looking at (much less trying to build) the actual fix.
http://koji.fedoraproject.org/koji/buildinfo?buildID=257107 should fix this.
No change here. $ uname -r 2.6.40.1-0.fc15.x86_64 (but the workaround still works) Let me know if I can try any other builds, or provide any other information.
how about 2.6.40.3 ?
Still no dice.
I have same problem After update kernel from RFRemix (2.6.38.8-35.fc15.i686.PAE) to RFRemix (2.6.40-4.fc15.i686.PAE) MMC card not work in internal cardreader on Fujitstu Lifebook E780, but SD card work perfectly.When I booting whith old kernel all work. After update to (2.6.40.3-0.fc15.i686.PAE) MMC not work too. dmesg on SD card /var/log/message: [ 1646.819824] mmc0: new high speed SD card at address b368 [ 1646.887901] mmcblk0: mmc0:b368 SD 1.90 GiB [ 1646.906684] mmcblk0: p1 dmesg on MMC card Aug 20 11:05:27 KesinBook kernel: [ 1789.919189] mmc0: error -110 whilst initialising MMC card Aug 20 11:05:27 KesinBook kernel: [ 1790.007110] mmc0: error -110 whilst initialising MMC card Aug 20 11:05:27 KesinBook kernel: [ 1790.091590] mmc0: new MMC card at address 0001 Aug 20 11:05:27 KesinBook kernel: [ 1790.092096] mmcblk0: mmc0:0001 000000 30.6 MiB Aug 20 11:05:27 KesinBook kernel: [ 1790.095031] mmcblk0: p1 Aug 20 11:05:27 KesinBook kernel: [ 1790.111112] mmc0: Got data interrupt 0x00200000 even though no data operation was in progress.
