Synopsis: [vm][panic] FreeBSD 8.0 RC2 with vm.pmap.pg_ps_enabled=1 kernel panic with makeworld
State-Changed-From-To: open->closed State-Changed-By: alc State-Changed-When: Mon Jul 5 20:51:26 UTC 2010 State-Changed-Why: Ultimately, it was found that the root cause of these crashes was a hardware bug in AMD Family 10h processors. In January, AMD documented this bug as Errata 383. AMD's recommended workaround is implemented in FreeBSD 8.1-RELEASE and 7.3-STABLE. As a workaround in earlier releases, either hw.mca.enabled or vm.pmap.pg_ps_enabled must be disabled. In some cases, such FreeBSD running as a virtual machine, the only option is to disable vm.pmap.pg_ps_enabled because the hypervisor controls the machine check hardware. http://www.freebsd.org/cgi/query-pr.cgi?pr=140338 _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
