Your attached dmesg of -RC3 is not -RC3, it is 8-STABLE.  At this point,
there have been changes between the stable/8 and releng/8.4 branches
enough say that the two have diverged, and the stable/8 code is _not_
what will be the 8.4-RELEASE.

While your issue does concern me, it is still unclear that this is
a problem with the upcoming 8.4-RELEASE.  Can you please try upgrading
to the releng/8.4 branch to see if this issue persists?

I installed RELENG_8_4 using cvsup (yes, I'm planning on updating) and got 8.4-BETA; this had the same behavior as 8-STABLE.

I tried booting the 8.3-RELEASE p8 kernel and got the same behavior, which makes me wonder if I had made some earlier mistake. I reinstalled 8.3-RELEASE p8 (world and kernel) from source and the system is now operating normally.

The differences between the kernel file I'm using and GENERIC are that I have options for "ipfirewall" and the "amd" driver for the AMD 53C974 and do not have devices "esp" nor "isci" (revised amd and iscsi). I'm going to revise my kernel file to be more up-to-date and will test that.

I'm not having problems with two other systems, one a Tyan S4882 with 4 single-core Opterons and a Tyan S2882 with two dual-core Opterons. Neither one uses the "fxp" driver; both are operating in x64 mode.
