I have been fighting this issue for months now. I am about to give up and go back to FreeBSD 4.x. I am looking for suggestions now.

1. What does this panic really mean?

I believe it implies that the kernel address space is exhausted, so when something tried to start up a new kthread, this failed because the kernel does not have enough memory to allocate a new stack for that thread.

2. Any ideas for a work around?  (kernel options, patches, anything)

Set up a cron job to run "sysctl kern.malloc > /var/tmp/kern_malloc" every minute or whatnot, and take a look at the last entry you get before the machine panics. That will help identify what is running your kernel out of memory.

3. Would a bug report actually get anywhere? (bad experiences in the past, 93809)

Maybe. You'll need to provide more information than just a dmesg, but even if you don't get a specific solution to your problem in the short term, having things in the PR database will help over the long term...
