The snapshot underwent A/B performance testing at Netflix and several people upgraded their laptops, desktops and home routers. Following problems were identified in this snapshot: 1) INVARIANTSs panic when using ipfw(4) dynamic rules. ipfw(4) users are recommended to cherry-pick d8a78048a246 and 29c3350f395a. 2) The AMD CPPC switched on by default instead of Cool`n'Quiet caused problems on certain hardware. For laptops see bug 292615. At Netflix A/B test we discovered that CPPC mode reports wrong frequency levels to powerd, which results in reduced performance. This problem is still not resolved. 3) Panic in vm_map code: https://people.freebsd.org/~novel/misc/core20260128.txt Note that this was discovered on pre-stabweek CURRENT. Only Roman seen this panic and there's no reproduce yet, so unresolved. The advisory code freeze is over. -- Gleb Smirnoff
