 Dear all,

 has there been any progress on this one? I'm seeing basically the same
 thing with FreeBSD 9, but in my case the problem turns up when I try to
 mount one of my ZFS filesystems built in a RAIDZ configuration on real
 hard disks connected over USB. The disks are fine, and the ZFS filesystem
 was unexported cleanly on a different machine. You can find the kernel
 messages from dmesg below.

 I'm willing to test patches, but it might take a while, since my machine
 (Netra T1 AC200 with a 500 MHz CPU) is not quite that fast when
 recompiling kernels.

 Cheers,

 Manuel

 This is what I get in dmesg:

 da10 at umass-sim7 bus 7 scbus12 target 0 lun 0
 da10: <WD Ext HDD 1021 2021> Fixed Direct Access SCSI-4 device=20
 da10: 40.000MB/s transfers
 da10: 1907727MB (3907024896 512 byte sectors: 255H 255S/T 60084C)

 ### start mounting the ZFS filesystem on USB disks here, then wait;
 ### there is a period of insense I/O and a variable amount of time you
 ### have to wait before the following messages appear:
