As I said its relatively new - I am running root on ZFS (and everything els=
e) and=20
had a reproduceable deadlock when I was using ZFS of Nvidia ATARAID so I=20
dropped the ATA RAID and are now running ZFS on the raw disks - It started =
occuring some
point after that (last two weeks).=20

The funny thing is if I break into DDB and wait app. 30 Sec the fans starts=
 spinning up and=20
running at very high speeds - e.g nothing should be running

Sysctl dev.cpu | grep temp - shows

dev.cpu.0.temperature: 70
dev.cpu.1.temperature: 71
dev.cpu.2.temperature: 68
dev.cpu.3.temperature: 69

I was trying to avoid to go back to running "pure UFS" again - but I guess =
I have to inorder
to eliminate ZFS as the potential source
