Dear all,
sorry to break the thread, but I did not have the originating message in my

I experienced *exactly* the same problem. 
As I'm using a modified kernel also, I'm not sure if this is an official

OpenBSD bug. Therefore, I switched the boxes back to GENERIC kernels for the

time being, waiting for one of them to possibly break down again. Since the

problem is not reproducable, it's hard to say if it only affects non-GENERIC

kernel builds.
We are running a classic carped firewall setup. As I can't file bugreports

with customized kernels, I just wanted to give you this note.
Differences between the customized kernel and GENERIC are:
# option                LKM             # loadable kernel modules

# option                EXT2FS          # Second Extended Filesystem

# option                MFS             # memory file system

# option                XFS             # xfs filesystem

# option                NFSCLIENT       # Network File System client

# option                NFSSERVER       # Network File System server

# option                INET6           # IPv6 (needs INET)

# option                PPP_BSDCOMP     # PPP BSD compression

# option                PPP_DEFLATE

# pseudo-device sppp    1       	# Sync PPP/HDLC

# pseudo-device ppp             	# PPP

# pseudo-device sl              	# CSLI

# pseudo-device pppoe   1       	# PPP over Ethernet (RFC 2516)
I also stripped down drivers I do not need, like soundcards, USB- and

firewiredevices or buses I do not have, pretty much just to the things that

are built into this box and really needed.
Kind regards,

Jens
