- Subject changed from Errors on Boot for Static Routes Startup Item in KVM environment to LOR on Boot for Static Routes Startup Item in KVM environment
- Priority changed from Normal to Very Low
It's a non-fatal LOR. Can leave this open to investigate since it's already here but we decided not to open individual Redmine for these, but to collect them on https://forum.netgate.com/topic/174821/reporting-lock-order-reversal-lor-backtraces
The error will disappear once we remove debug options from the kernel, but it may still be worth investigating.
