Bug ID: 230722
Summary: [nvme][resume] Delay and possible deadlock after
resume
Product: Base System
Version: CURRENT
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: b...@freebsd.org
Reporter: go...@freebsd.org
CC: i...@freebsd.org, jimhar...@freebsd.org
When resuming from S3 sleep any disk activity stops for around 30 seconds and
kernel prints a bunch of error messages from NVME. Eventually, the system
resumes normal operations. I also saw this scenario resulting in deadlock
although can't reproduce it reliably anymore.
Error messages printed by the kernel:
nvme0: Resetting controller due to a timeout.
