Thanks, will do. Is it supposed to fix this?

As you can see geli worked fine, but at some point it stops working and
can no longer attach new volumes.

I'm also seeing interrupt storms for USB devices, when I plug in the
drives into xhci0 instead of xhci1 (but this needs more testing, first I
need to get that damn zpool moved)

xhci0: <Intel Panther Point USB 3.0 controller> mem 0xe0720000-0xe072ffff irq 21 at device 20.0 on pci0
xhci0: 32 byte context size.
usbus0 on xhci0
xhci1: <XHCI (generic) USB 3.0 controller> mem 0xe0500000-0xe050ffff,0xe0510000-0xe0511fff irq 19 at device 0.0 on pci5
xhci1: 64 byte context size.
usbus2 on xhci1

xhci0 at pci0:0:20:0:      class=0x0c0330 card=0x72708086 chip=0x1e318086 rev=0x04 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '7 Series/C210 Series Chipset Family USB xHCI Host Controller'
    class      = serial bus
    subclass   = USB
xhci1 at pci0:5:0:0:       class=0x0c0330 card=0x00000000 chip=0x8241104c rev=0x02 hdr=0x00
    vendor     = 'Texas Instruments'
    device     = 'TUSB73x0 SuperSpeed USB 3.0 xHCI Host Controller'
    class      = serial bus
    subclass   = USB


What's with the 32 vs 64 byte context size? And do you know of any problems
with the Intel controller?

Cheers,
