bug. Repeated SATA NCQ timeouts and link resets on Loongson 3A6000 root linux #214
Description
On the Loongson 3A6000 platform, the onboard SATA controller can detect disks correctly during root linux's early boot, and the root filesystem on sda mounts without issues. However, approximately one minute after the system finishes booting, the SATA subsystem begins failing. The driver enters repeated NCQ command timeouts, performs link resets, and eventually disables the device. The filesystem on the affected partition is forced into read-only mode and is later unmounted.
Because the root domain’s SATA device becomes frozen, any non-root Linux guest using a virtio-blk device backed by this partition also loses its root disk and fails to mount its virtual filesystem.
Disabling virtio-blk in the guest does not prevent the SATA failure.
root linux's rootfs using sata sda is ok at boot time:
