Hello all,
I am using a custom board based on var-som-om44 which is using omap4460 SoC. I am sing Android ICS on it.
My device is booting from microsd card including x-loader,u-boot and kernel. It is working fine most the times. but at some point I am getting following error. Then I take out the card and plug it to my Ubuntu machine and then I do safely remove and then the same card is working fine.

I am also attaching full boot logs. 6765.new_mmc_logs.txt
It is also printing some kernel interrupt warnings. They are in full logs in attached file.
I am not sure what is the problem. Can any one provide me some pointers for hat should I check/do to resolve this problem?
Any help will be appreciated.

Pratik Rathod
