System : OpenBSD 6.5
Details : OpenBSD 6.5-current (GENERIC.MP) #1368: Sun Apr 21

Architecture: OpenBSD.i386
Machine : i386
>Description:
Hi, since my last update I have regular panic crashes. 4 in two days.
At least 3 of them, with certainty, occurred while I was accessing the
Internet via my smartphone connected to my OpenBSD WiFi access point
through my Allways-on VPN isakmp/ipsec/nppp relaying traffic in Tor.
This setup works for years.
The machine then displays something like:
uvm_fault(0xd34e5f3c, 0x0, 0, 2) -> e
kernel: page fault trap, code=0
Stopped at kqueue_scan+0x246: movl %eax,0(%ecx)
ddb{1}>
The USB keyboard is then not functional to provide more information.
I had not noticed any malfunction on the previous kernel I was using:
OpenBSD 6.5 (GENERIC.MP) #1353: Thu Apr 11 08:28:28:28 MDT 2019
The problem I am experiencing is very similar to the one Aaron Bieber
encountered in this message:
https://marc.info/?l=openbsd-bugs&m=149935139022501
The resolution mentions problems with NET_LOCK...
2 commit since 11/04 mention NET_LOCK (if it helps):
