Rock Pi S ext4 panic


StevePER

Recommended Posts

Armbianmonitor:

My Rock Pi S logs a NULL pointer dereference in the ext4 module after running for 1 to 3 hours. Subsequently existing processes continue to run but it appears that new processes can't start (eg I can't ssh in).

The filesystem is on a new Sandisk Ultra Plus microSD card.

As a test, I remounted the root filesystem read/write and the board ran flawlessly for 10 hours. When I get time I will try rebuilding the image with the root filesystem on F2FS.
