Unfortunately my machine crashes every hour or so when I run 2.6.25, both with the home build kernel and with the Debian kernel, this makes it impossible for me to do any real testing. The SD card works on the home build kernel, but not on the Debian kernel, I will wait for 2.6.25 to become stable for me and then find the difference between the two build that prevents the SD card from working on one of them. I have also tried to compile 2.6.24 for myself now in order to see if the SD would work there, it didn't, but I got a reaction in the dmesg now: mmc0: card claims to support voltages below the defined range. These will be ignored. mmc0: SDIO card claims to support the incompletely defined 'low voltage range'. This will be ignored. mmc0: error -110 whilst initialising SDIO card This might explain what the problem is? Anyway, thanks for your time, I will just wait a little longer as it almost works now, -- Kim Hansen Vadgårdsvej 3, 2.tv 2860 Søborg Fastnet: 3956 2437 -- Mobil: 3091 2437
