Is anyone seeing deadlocks with USB devices on 8 RELEASE? This is a
definite regression from 7.1 and 7.2 for me. I had just upgraded my
laptop an HP NX6125, AMD Turion 64, ATI Xpress 200M Chipset.
Anytime I insert or remove a USB device, WIFI chipset (broadcom with
ndis driver)/Bluetooth, External USB hard drive, The system becomes
completely unresponsive. If you look at the top output below my
attempt to run a zpool import on the Western digital hard drive I have
has stopped in tx->tx and I can't kill the process.
