Description

Many zfs threads are stuck in zio_wait() for long time (2 minutes or more) and the system is completely hung:

# echo "::stacks -c zio_wait|::findstack -v" \\
> | mdb 1 | grep zio_wait \\
> | sed -e 's/.*0x5b(\\(.*\\))/\\1::zio/' \\
> | mdb 1 | grep -v ADDRESS

This happened on my desktop with OpenIndiana hipster installed (with illumos from September 1st).

The crash dump size is 1.3GB. I'll provide it on request.
