Comment 4 for bug 1531653

> Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

This is the first time I've tried using the SD card. So I can't say if any system changes have affected it.

However, the fact that my SD card reader doesn't show up when booted into SystemRescueCD, and it does show up when booted into my friends MBP, makes me think it's not a system configuration issue.

I tried, but I'm using a ZFS filestystem for my root. I tried to build but I guess there are issues due to my relying on "out of tree" modules. I'm not familiar enough with building kernels to know how to proceed at this point. If you could point to instructions that would tell me how to use a mainline kernel with my dkms zfs module (so I can boot), I'd be happy to give it a try.
