I can reproducibly panic it using the following sequence of three steps: # dd if=/dev/zero of=sparse_file bs=1M count=2000000 # zpool create testv28 raidz1 ad20 ad26 `pwd`/sparse_file # zpool offline testv28 `pwd`/sparse_file At step 3, I panic every time. I am attempting to get a crash dump, but for whatever reason, the dump appears to be hanging instead of making any progress. - Rich
