https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=207621 Bug ID: 207621 Summary: SATA SSD / Allwinner A20 Product: Base System Version: 11.0-CURRENT Hardware: arm OS: Any Status: New Severity: Affects Some People Priority: --- Component: arm Assignee: freebsd-arm@FreeBSD.org Reporter: fulda@seznam.cz This bug affect boards with Allwinner A20 chips. Once they have attached SATA SSD disk (no necessary to mount, only plugged in), then you will have troubles with reading more files from SD card. I did small experiment - download last image (same experience with previous one), boot, and without any modifications start reading files from SD. Attached sata ssd have no UFS/FAT partition and no any partition is mounted. (my hardware is Banana PI M1) Here is three examples: read disk using tar with transfer data to another process (wc) and without (to dev/null) Outputs from my experiment follows.
