- Priority changed from High to Normal
That's due to INVARIANTS in the kernel which is only a temporary measure to gather information while other issues are being debugged. It's going to be removed shortly.
- Status changed from New to Feedback
- Affected Version changed from 2.5.x to 2.5.0
INVARIANTS has been removed from the kernel, try the next new snapshot.
A few minutes ago I updated my system via the GUI to today 1250. The router did restart properly! and seems to work normally.
- Status changed from Feedback to Resolved
- Status changed from Resolved to New
- Target version changed from 2.5.0 to 2.5.2
A fix has been committed to FreeBSD, we will make sure it gets into 2.5.2.

The list of ports in configuration path shall be protected by locks,
epoch shall be used only for fast path. Thus use LAGG_XLOCK() in
lagg_[un]register_vlan. This fixes sleeping in epoch panic.

(cherry picked from commit e1074ed6a08033ee571b4bedb3ffe6049a4a7361)
- Subject changed from Problems with laggs in recent snapshots to Panic configuring LAGG+VLAN interfaces when using a kernel with ``INVARIANTS``.
- Release Notes changed from Default to Force Exclusion
Updating subject but excluding from release notes since it wouldn't affect any potential release, only debugging kernels sometimes present on development snapshots.
- Status changed from New to Feedback
The relevant commit for this should be present on a build dated after this comment.
Given the barrier to testing this (requires compiling a custom kernel with INVARIANTS in it), we can just close it after a couple days if there is no feedback.
Testing that LAGG and LAGG+VLANs still work is likely sufficient.
- Status changed from Feedback to Closed
