About a week ago I traded one of my HD2400's against a HD51 (someone I knew needed more than 2 tuners while I didn't but would like to be able to watch UHD, so good trade)
When I got the HD51 it had another image installed (don't know which as I flashed it immediately with OpenPLi)
When I flash it sometimes after startup it gives a GSOD (then when I pull the plug and it reboots no problem anymore untill the next reflash).
I found the following peculiar entries in the log (also enclosed)
<2>[ 179.274814] EXT4-fs error (device mmcblk0p3): ext4_mb_generate_buddy:758: group 64, block bitmap and bg descriptor inconsistent: 8192 vs 4112 free clusters<4>[ 179.308718] JBD2: Spotted dirty metadata buffer (dev = mmcblk0p3, blocknr = 1).
