The keyboard LEDs cycle, the disk runs and X returns. Good to hear, Ted .. I thought it was just me :) Your symptoms appear entirely identical to mine as posted on Dec 13th to mobile@ and acpi@, see thread 'Thinkpad T23 60 second stall on resuming 8.0-RELEASE/i386' http://lists.freebsd.org/pipermail/freebsd-acpi/2009-December/006192.html Nate Lawson thought it an ATA rather than an ACPI problem and I assume he's likely right, but I've had too much $work (and too little solar power during an exceptionally wet summer) to follow it up. > I don't recall this stutter under FreeBSD 7.

I'd recently upgraded t23's BIOS too. Since then I took 7.0-RELEASE to 7.2-STABLE (28 Dec) and still have no such issue on 7, although the ATA messages on resume are marginally different. I haven't yet upgraded my 8.0-R to -STABLE; going by this it seems that's unlikely to help now. In case relevant, my ad0 is a 120GB Fujitsu MHV2120AH, but your TOSHIBA MK4026GAX looks more likely to be the original disk? > I have attached a trace of a boot -v going through the cycle.

In that post I mntioned some other symptoms regarding devd and "calcru: time went backwards .." messages, but I suspect those were side-effects. Once it resumes after the one-minute delay I've noticed no other issues, but can't claim to have spent much time exercising it. > Any help would be appreciated, and I'm happy to provide more data on > request. I've no time to spend on hunting this now, and know nothing about ATA anyway, assuming that's where the problem lies, but I'll be quick to test any suggested solution/s! cheers, Ian
