Bug ID: 210683
Summary: [iscsi] FreeBSD panics almost immediately after
starting ctld
Product: Base System
Version: 11.0-CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: e...@norma.perm.ru
FreeBSD panics almost immidiately after starting ctld.
FreeBSD holds 24 disks for VM resources, which are organized on zfs pools;
zvols are created which are distributed via iSCSI. FreeBSD was up for several
days, and then (all of a sudden, after some good production use) this panic
appeared.
Panic screen is attached.
Panic is 100% reproducible after rebooting.
I can also provide the direct server access if needed.

disks are used in JBOD/Passthrough mode.
I have a dumpdev configured, but savecore sayd there's no core. Either my swap
device is smaller, or there's just no core.
