I found this patch (by searching the mailing list archives for cvs-all postings with the date Feb. 4, 2005), and it applied cleanly, but now syslog is getting spammed with: microuptime() went backwards (443643.141593 -> 443642.210394) microuptime() went backwards (443647.382021 -> 443640.104932) microuptime() went backwards (443648.320102 -> 443847.981025) ...ad nauseam. It looks like the timecounter code needs to be modified to account for the temporal distortion. Either that or maybe my crystal ball interface isn't working properly (usbd has been kind of flaky about detecting it lately).
