This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux major release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion. I was able to read the SD card without problem on a Dell 1420 running Fedora 13. The dell had the following reader (from lshw):
*-generic:0
description: SD Host controller
product: R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter
vendor: Ricoh Co Ltd
physical id: 1.1
bus info: pci@0000:03:01.1
version: 22
width: 32 bits
clock: 33MHz
capabilities: bus_master cap_list
configuration: driver=sdhci-pci latency=64
resources: irq:18 memory:fe4ff400-fe4ff4ff
The Dell 1420 had the following information about the SDHC driver in /var/log/messages:
Jun 13 13:51:18 tandem kernel: sdhci: Secure Digital Host Controller Interface driver

On the T510 see the following information about the SDHC driver in /var/log/messages:

This issue has been proposed when we are only considering blocker issues in the current Red Hat Enterprise Linux release. It has been denied for the current Red Hat Enterprise Linux release. ** If you would still like this issue considered for the current release, ask your support representative to file as a blocker on your behalf. Otherwise ask that it be considered for the next Red Hat Enterprise Linux release. ** This problem is fixed in the 2.6.32-71.7.1.el6.x86_64 kernel that the machine is currently running. Cards now being mounted and working properly on the machine: Nov 22 10:17:59 cannondale kernel: mmc0: new SDHC card at address 0007 Nov 22 10:18:00 cannondale kernel: mmcblk0: mmc0:0007 SD08G 7.48 GiB Nov 22 10:18:00 cannondale kernel: mmcblk0: p1 The read benchmark in the "Disk Utility" and cp also work without error on the mounted device. |
