zpool resilver restarting

[Wes Morgan]

I just did a zpool replace on a new drive, and now it's resilvering.
Only, when it gets about 20mb resilvered it restarts. I can see all the 
drive activity simply halting for a period then resuming in gstat. I see 
some bugs in the opensolaris tracker about this, but no resolutions. It 
doesn't seem to be related to calling "zpool status" because I can watch 
gstat and see it restarting... Anyone seen this before, and hopefully have 
a workaround...?

The pool lost a drive on Wednesday and was running with a device missing, 
however due to the device numbering changing on the scsi bus, I had to 
export/import the pool to get it to come up, the same for after replacing 
it.
