Many PineBook Pro users have reported issues with NVMe SSD drives, including random Linux lockups and crashes. Some of these issues are related to the [https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=712fa1777207 RK3399's errata] that disables Gen2 (5 GT/s) speed for the PCI Express link used by the NVMe SSD, reducing it down to Gen1 speed (2.5 GT/s). However, as of December 17, 2020, Linux distributions that use mainline Linux kernel still configure the PCI Express link to run at Gen2 speed, which requires [https://forum.pine64.org/showthread.php?tid=11683 manual reconfiguration] to Gen1 speed in case system instability is experienced.

Some PineBook Pro users have reported issues with the default settings for the APST (Autonomous Powe State Transition) power saving, which cause an NVMe drive to disappear from the system or lock up after a certain period of time.
