Description
|
We saw a single instance of BAD TRAP during TX setup (which creates
TX local zones prior to test run) in snv_101 on v20z - then later
reproduced singluarly on a "off-shelf" amd64 and a iwashi (Sun-Storage-7110)
platform - neither of these could produce a coredump as they continuially
panic. This wasn't seen before in previous builds of nevada.
The operating system root FS is ZFS. There is putback made to ON that could be
the cause for this. See comments.
