That's interesting; since my original report last December I discovered that same behaviour with 8.0-R. During the 60s resume stall period, iff I'd suspended from a VTY, I found I could slowly (like maybe 3 seconds per character echoed) type a command, and some commands - possibly those cached? as there's no HD access - would run after another few seconds. In this way I discovered that 'date' commands reported the time some seconds after the resume (perhaps hours ago, or yesterday) until the stall ended, disk light flashed and normality resumed, sometimes with "calcru: time went backwards .." messages, most often for devd. Since upgrading to 8.1-STABLE that clue? has gone; nothing typed is echoed. Are you referring to 8.1-RELEASE or to 8-STABLE as at some date? > This has been like this in 7.0 too (except I don't know if it ever > recovered the speed; I remember shutting it down as soon as I saw how > slow it is). That's a difference then; 7.0-R then 7.2-STABLE (late December, anyway) had no such issues here on my T23. When it clears up after a wet week and I have some spare power again I'll try building a debug kernel, perhaps omitting and kldoading USB, and do some more tests before reporting further, probably in mobile@ and acpi@ again. I'll copy you and Ted when I do so. Thanks, Ian
