Hi,
I recently got this panic on an 8/27 snap 3.0 current machine:
panic: vm_page_unwire: invalid wire count: 0
Looking through the PR's I see that there is one open on this (PR
#5839), opened way back on Feb 24 of this year. This is the second
time my machine has crashed in this way in a month's time.
Can anyone tell me if this bug has been fixed in current, or does it
still linger?
Thanks,
-Brian
