Just to check if I'm the only one seeing that:

I built 5.99.15/amd64 from sources around today 1300 UTC and installed it.
A few minutes later, the remote connection reset.

Later when I got home, I sat in front of the machine and created network
and hard disk traffic + X; the machine reset a few times, always in a very
short time frame (< 1h, usually less than 15 min).

I had inserted a new hard disk today as well, so I took it out, but the
resets happened nevertheless.

I have ddb.onpanic?=0 in my sysctl.conf, so perhaps it's just a kernel panic.

It also happened when I went back to my previously stable 5.99.14 kernel
from 20090615 with the 5.99.15 userland; with and without the hard disk.

I now went back to 5.99.14/20090615 completely (kernel and userland) and
the resets stopped (even with the hard disk and heavy hard disk activity).

Anyone else have trouble with -current right now?

Yep, same here. While, most of the time, there was a reset; i
encountered some cases where it was badly stuck (no ddb console
access) and needed a power cycle :-(

I just reverted the Ephemeral mapping commit, and was able to run
without any problem for a while ... I'm still crossing fingers.

Did you guys get any further in debugging this? I'm going to revert to
see if that helps my hangs in amd64-current.
