These look suspicious.

Perhaps the  acpicpu driver is the culprit. 5.8 appears to of added the
following:

acpicpu(4) http://www.openbsd.org/cgi-bin/man.cgi?query=acpicpusec=4 uses
ACPI C-state information to reduce power consumption of idle CPUs.

A  “cool” feature imho that might add life to a fanless.

That'll make his box idle cooler, but that's unrelated to a panic in
the SRP bits.

bpf_mtap/SRP on -current/amd64 panics after a few minutes

2015-08-22 Thread Mattieu Baptiste 
Hi,

I just upgraded my main router to -current (a PC-Engine APU, dmesg at the end).
It panics after 5 minutes or so. It seems relative to the commit
making bpf_mtap using SRPs.

I'm bridging vlan/vether interfaces:
$ cat /etc/hostname.bridge0
add re0
add vether0
up

$ cat /etc/hostname.bridge1
add vlan0
add vlan3
up

$ cat /etc/hostname.re0
inet 192.168.42.1 255.255.255.0 NONE group internal
inet6 alias 2a01:::::1 64

$ cat /etc/hostname.vether0
inet 192.168.42.2 255.255.255.0 NONE group internal -inet6

$ cat /etc/hostname.vlan0
vlan 100 vlandev re0 -inet6

$ cat /etc/hostname.vlan3
vlan 100 vlandev re2 -inet6

Here are the panic, trace, ps and dmesg:

panic: srp_leave: unexpected ref 0x80235700 via 0x80077448

RUN AT LEAST 'trace' AND 'ps' AND INCLUDE OUTPUT WHEN REPORTING THIS PANIC!
