https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211713 --- Comment #64 from Warner Losh <imp@FreeBSD.org> --- 'sync' will force all the dirty buffers to be scheduled in the nvme controller and won't return until they are complete. There are no other 'flush' operations needed as the errors are that we suspend while we have pending I/O in the nvme controller. That might need to be attended to, but it isn't currently. But a suspend / resume bug is very different than this bug. Please file a new bug to track that. This bug is, during normal operations, something bad happens, and we stop being able to talk to the NVMe drive and error recovery is insufficient to cope. -- You are receiving this mail because: You are the assignee for the bug.
