Hi,
This week I updated a machine from 7.3 to 7.5. Almost immediately it
started panicking constantly. The machine runs a webserver on a wg(4)
interface and receives a mild amount of traffic. I turned off
wireguard, moved the wg config to a vmm(4) virtual machine, and
immediately the host stopped crashing and the VM started crashing.
The problem still occurs on -current. It reliably lands in ddb after a
few hours (or, sometimes, less than a minute) of uptime.
Here are four traces from -current. They all look pretty different to me,
but I don't know what I'm looking at.
