Subject: Re: SDHC card affected by preemption model in 2.6.35

Hello Venkat, Hello Mathieu,

We get the timeout Problem every time:
[    1.888732] Waiting for root device /dev/mmcblk0p2...
[    4.193603] mmc0: error -110 whilst initialising SD card

Right now the issue occurs with following cards CONFIG_PREEMPT=y enabled:

- SanDisk 4GB micro SDHC Class 2
- SanDisk 2GB micro SD


These cards worked fine:

- Transcend 2GB micro SD
- Transcend 4GB micro SDHC Class 6
- SanDisk 4GB micro SDHC Class 6 (Mobile Ultra)


Thanks,
Johannes
