I gave it a try.
[arcmsr.c]
- bus_setup_intr(dev, irqres, 0, arcmsr_intr_handler, acb, &acb->ih, NULL)) {
+ bus_setup_intr(dev, irqres, INTR_MPSAFE, arcmsr_intr_handler, acb, &acb->ih, NULL)) {
The good news is there was no obvious stability issue; the tests completed
successfully.
But there was no real performance change either. blogbench results were
624 / 176300, in line with previous ones.

On the contrary, shouldn't performance be higher if the disks are not touched ?
Looking at iostat history, newfs pushed almost 8000 iops to the raid volume.
blogbench was much lower at first and the number of iops was almost divided
by ten after some time.
I've attached a log of iostat /dev/da0 1
Two activity periods are shown in the file:
- newfs_hammer -L RAID_VOL /dev/da0
- blogbench -d /mnt/blogbench
