• If I use USB flash stick it works well
• On Macbook Air mid 2012 boots well from SD-card

I found this error message by grep here https://github.com/grml/live-boot-grml/blob/master/components/9990-main.sh#L87 and have no idea how to debug/fix/workaround.

@mibori thanks for reporting this. Is this an external USB card based SD-card reader you're trying to boot from? Can you please try identifying what driver is relevant for it? lshw/hwinfo/.... should be your friends (or invoke grml-hwinfo as root and send me/us the resulting tarball).

This is builtin SD card reader. After few minutes I will send you hardware report by grml-info on [email protected].

P. S.: Sorry for the long answer.

Another case.

I have keyboard with two additional USB ports. If I insert USB-stick to the keyboard, I have same error.
