I just upgraded my package build machine to: FreeBSD 15.0-CURRENT #110 main-n268161-4015c064200e from: FreeBSD 15.0-CURRENT #106 main-n265953-a5ed6a815e38 and I've had two nvme-triggered panics in the last day.
nvme is being used for swap and L2ARC. I'm not able to get a crash dump, probably because the nvme device has gone away and I get an error about not having a dump device. It looks like a low-memory panic because free memory is low and zfs is calling malloc(). This shows up in the log leading up to the panic: Feb 12 10:07:41 zipper kernel: nvme0: Resetting controller due to a timeout a nd possible hot unplug. Feb 12 10:07:41 zipper syslogd: last message repeated 1 times Feb 12 10:07:41 zipper kernel: nvme0: resetting controller Feb 12 10:07:41 zipper kernel: nvme0: Resetting controller due to a timeout a nd possible hot unplug.
