Bug ID: 290304
Summary: panic: malloc(M_WAITOK) with sleeping prohibited in
zv_request_task_create
Product: Base System
Version: 16.0-CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
I can reliably trigger this panic on an unmodified 16.0-CURRENT kernel.
Steps to Reproduce
==================
1) Install 16.0-CURRENT from today (git 654a3aa9a1d)
1.5) create a least one zvol somewhere in zroot. I'm not sure if this is
required, but I do have zvols there.
2) cd /usr/tests
3) sudo kyua test sys/geom/class/uzip/1_test:main
