I first noticed this panic when conducting hot-swap tests. However,
now I see it every hour or so, even when all drives are attached and
no ZFS resilvering is in progress.
Repro:
- Pull a drive
- Wait for drive absence to be acknowledged by fm
- Physically re-add the drive
This machine contains two LSI 9240-8i SAS controllers running imr_sas
(the driver from LSI's website) and a umem NVRAM card running the
nvdisk driver. It also contains an SSD L2ARC.

I'd file this directly to the bug database but I'm waiting for my
