            Bug ID: 268416
           Summary: Crash on boot while tasting large USB ZFS disk
           Product: Base System
           Version: 13.1-RELEASE
          Hardware: amd64
                OS: Any

          Priority: ---

core.txt.2 from this morning's crash

My system has a large (1TB) external USB disk (GPT label, full disk allocated
for on ZFS file system).  On booting up, it can take anywhere from a few
seconds to half a minute for the USB disk to come on line.  When it does come
on line, soon afterwards the ZFS subsystem detects it and mounts it.  But
rarely (although unfortunately twice in the last three days) the system crashes
while mounting the disk.  The attached core.txt.2 from this morning has a panic
I've never seen before: VERIFY3(0 == nvlist_add_nvlist(nvl, name, val)) failed
(0 == 22).  The core.txt.1 file from the day before yesterday that I'll attach
next is a page fault in kernel mode.

Please let me know any other information needed.

I've been using ZFS for almost as long it has been part of FreeBSD, but only on
my main file server that is on all the time.  It's only recently that I've
started using it on my desktop (that gets booted up once or twice per day) or
on a USB disk.
