I use Lenovo’s nvme SSD (PCIe GEN3 x4, 250g), and the system can recognize it. But when I do the hard disk test and write 20g files, the system will crash randomly.
I don’t know if it’s the driver problem, or the SSD problem, or the rockpi4b problem? I used rockpi4b v1.4.
Test command: sync; / usr / bin / time - P bash - C “(DD if = / dev / zero of = / MNT / files / test. DD BS = 1000K count = 20000; sync)”
Always prompt “kernel panic - not syncing: bad mode”, I don’t know what it means
Crash message：
