Bug ID: 295387
Summary: panic: make_dev_sv: bad si_name (error=17,
si_name=cam/ctl1.0)
Product: Base System
Version: 16.0-CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
I found this panic this morning, on the latest 16.0-CURRENT build
(30f500e97b5). Note that to reproduce it, the "-v parallelism=8" is essential.
I cannot reproduce it with the default parallelism of 1. Also, note that the
cfiscsi module was not loaded at the time.
Steps to Reproduce
==================
cd /usr/tests/usr.sbin/ctladm
kyua -v parallelism=8 test
Stack Trace
