Guylhem,
I trieds to install both of your kernels, and I have the same problems with both.
When the kernel starts, I have a "Cramfs wrong magic", than I have a lot "inode #.. was a directory with children, remving those too".
The sharp_mmcsd is loaded, but then I receive a lot of "pxa_sd_stopclock: clock stop time out"
Than I have a lot of "VFS: Disk changedetected on device mmcd (60,1)"
At the end the system starts and seem to work corrcetly, apart that I cannto see the SD.
I tried with 2 cards (both ext2), with the same result.
I can forward my dmesg, if this could be useful, just remember me how to output it to a file
Thanks,
cheers,
Adalberto
