Title:
Test 069 from ubuntu_zfs_xfs_generic causes kernel panic on Artful
zKVM
Status in linux package in Ubuntu:
Invalid
Bug description:
This issue can be easily reproduced on our zKVM node (s2lp6g004) by
running the ubuntu_zfs_xfs_generic test suite.
The "virsh list" command will show that it's "crashed" after this
happens.
