Security Advisories &security; Errata Notices &errata; Open Issues An issue was discovered with Amazon® EC2™ images which would cause the virtual machine to hang during boot when upgrading from previous FreeBSD versions. New EC2™ installations are not affected, but exisiting installations running earlier releases are advised to wait until the issue is resolved in an Errata Notice before upgrading. An Errata Notice to address this is planned following the release. &os;/&arch.i386; installed on ZFS may crash during boot when the ZFS pool mount is attempted while booting an unmodified GENERIC kernel. A system tunable has been added as of revision r286584 to make the kern.kstack_pages tunable configurable without recompiling the kernel. To mitigate system crashes with such configurations, chose Escape to loader prompt in the boot menu and enter the following lines from &man.loader.8; prompt, after an OK: set kern.kstack_pages=4 boot Add this line to /boot/loader.conf for the change to persist across reboots: kern.kstack_pages=4 A bug was diagnosed in interaction of the pmap_activate() function and TLB shootdown IPI handler on amd64 systems which have PCID features but do not implement the INVPCID instruction. On such machines, such as SandyBridge™ and IvyBridge™ microarchitectures, set the loader tunable vm.pmap.pcid_enabled=0 during boot: set vm.pmap.pcid_enabled=0 boot Add this line to /boot/loader.conf for the change to persist across reboots: To check if the system is affected, check &man.dmesg.8; for PCID listed in the "Features2", and absence of INVPCID in the "Structured Extended Features". If the PCID feature is not present, or INVPCID is present, system is not affected. vm.pmap.pcid_enabled=0 - The Release Notes errorneously states the + The Release Notes erroneously states the WITH_SYSTEM_COMPILER &man.src.conf.5; option is enabled by default, however this was disabled prior to the final release build.
