https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=294130 Bug ID: 294130 Summary: Kernel panic when running Kyua test aio/aio_test:vectored_zvol_poll, in zvol_geom_access Product: Base System Version: 16.0-CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: cracauer@cons.org When you run all the kernel tests on 16-current, it panics with a page fault when running test aio/aio_test:vectored_zvol_poll The central function involved seems to be zvol_geom_access(). I have INVARIANTS on, but that doesn't seem to be matter. Note that to reproduce this you have to have the zfs kernel module loaded before starting the tests.
