@WereCatf Cool, let me know if it works please

I am having the same issues and the following errors when running dmesg as well:
[ 542.418508] mmc0: new high speed SDHC card at address 1234
[ 542.424731] mmcblk: probe of mmc0:1234 failed with error -28
I have emailed onion and am just waiting for a reply. Anyone found a solution/workaround yet?
