So, even if the code was updated to look at and honor RTD3E, it wouldn't help in this case. :-( Perhaps we should make the SHN wait time configurable? Default to 5 seconds, overridden by RTD3E if present, overridden by per-device sysctl if set? -- You are receiving this mail because: You are the assignee for the bug.help
