Thank you very much! Yes. That is possible - and it fixes the delay. I would not have thought to look for that; I would not have expected piixide and ahcisata to be similar enough that a BIOS setting could personality-swap between them. > I'm guessing this is some quirk of the pciide(4) and piixide(4) > drivers. Sounds like; they presumably have a bug somewhere in some delay calculation. But at least I have something approaching a workaround. > Not to be too flip, but do you expect these machines to reboot > frequently in production? Often enough that my colleague on the customer-interface side of things thinks twenty seconds of delay on reboot is a problem. > If not, then I'd probably live with the delay on reboot as at this > point, [...] Me too. I didn't even realize it was there until they pointed it out to me; I don't really notice twenty seconds more delay when the typical peecee BIOS imposes anywhere from thirty seconds to five minutes before it even starts to boot. I'm obviously not part of their target market for this thing. > I'd be concerned that any fix I came up with for it would have > implications down the road which might be more serious and more > impactful on operations. Fair concern. > I certainly understand the need to know what's going on, but if a > machine only reboots once or twice a year in production, then ... Also fair. But I think once a day is the very fewest reboots we're likely to see for this, though I'm not really all that in touch with the user base, so.... I'll push this over to them and see if it's an acceptable workaround to poke the BIOS settings on the existing installed base. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
