https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D238585 Bug ID: 238585 Summary: Intel Bay Trail/Braswell eMMC timeouts Product: Base System Version: 12.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: paul.le.gauret@gmail.com Running latest FreeBSD 12.0-RELEASE on an "Atomic Pi" board (Atom x5-Z8350 based). System is installed on the internal eMMC, filesystem is ZFS. Every once in a while (sometimes hours, sometimes days) the system freezes = with no emmc disk IO possible. The system log shows the following happening. Jun 11 05:27:11 atomicbsd kernel: sdhci_acpi0-slot0: mmcsd0: Got AutoCMD12 error 0x0001, but there is no active command.
