Description sigsys 2020-05-05 08:22:56 UTC
After updating a 12-STABLE machine from r358905 to r360653, I sometimes get panics not long after boot.  Seems like it might be happening about half of the time.  The system seems stable (so far) if it doesn't crash not long after boot.  The problem might have been there before that upate but I just didn't notice it because I got lucky.

[59] KDB: enter: panic
Comment 1 sigsys 2020-05-05 09:00:54 UTC
After some testing, it seems to only panic when it tries to import all of its pools on boot.  This computer has 3 pools: a main 2-way SSD mirror pool it boots from, a small 1 SSD pool (SSD also has a swap partition on it) and a 2-way HDD mirror pool.  Preventing the HDD pool from being imported automatically on boot prevents the panics.  And importing it manually a little bit after booting also does not panic.  Also, there are no kernel error messages at any point (even in the cases where it does panic (well, apart from the panic)) and nothing bad in zpool status.
