    I don't have huge amounts of detail. I'm sort of writing this to see if
    I can get a rough idea how likely it is these items are already fixed
    in the pending 5.2 release.

    Case #1:

    I have an Asus P5A based machine that I recently upgraded to
    RELENG_5_1. When I was done, I found that when it was shutting down,
    just at (what I perceive to be, anyway) the last step before it would
    reboot, it would go into what appeared to be a trap loop of some sort.
    It would quickly scroll 'trap 12' frames and then hang. The only
    recovery is to press the reset button.

    This isn't really a big pain, but it does mean that I can't remotely
    reboot this machine at all.

    It must be at least happening after the filesystems are dismounted,
    because they always come back up clean.

    I note that this machine has to have kern.timecounter.hardware="TSC" in
    sysctl.conf to keep the clock from running at double speed. Is this
    something fixed in 5.2 or is this something unfixable except in
    hard/firmware?

Case #2:
This is an older machine with a USB 2.0 PCI controller card and an 
external USB 2.0 disk enclosure. Excerpts from dmesg.boot:

Shortly after disk I/O begins on the USB disk, there is a fatal trap 
panic and reboot. This disk/controller pair worked just fine under 
4.8-RELEASE, albeit not at high speed.

Should I not worry about these and just wait for 5.2?
Thanks in advance.
