Well, after much tinkering and tweaking, the verdict is still the same. ACPI is totally unusable for my IBM A30p (1.16 BIOS) with FreeBSD 5.0-RELEASE. Furthermore, if I shut off ACPI at boot time using: unset load_acpi set hints.acpi.0.disabled="1" The kernel locks up (freezes. nothing happens. No DB> prompt.) right before it detects the keyboard controller. Thus, I cannot use APM either. My 4.8 kernel wouldn't even detect APM at boot time (yes, it was compiled in). In addition, 5.1-BETA and 5.1-BETA2 both panic on boot of the generic prepackaged install CD kernel, so I can't very well test out the newer ACPI support and see if it's working better. I really need some kind of power management support if I'm going to do any amount of usefull work on this laptop. Therefore, I think I'm going to have to give Linux a try. Perhaps linux's kernel won't detect APM and won't support ACPI either, but I've read three different websites that claim working APM support under linux for the IBM A30p. (Granted, I most certainly have a newer BIOS than they had when they wrote those web pages, but it appears that Linux is my last chance for working power management under a UNIX-like OS.) Anyway, it appears to me that 5.x has a long way to go before it's of the same stability as 4.x. On my servers and even on this very IBM A30p laptop, 4.x hasn't given me a single panic, crash, or other failure. (But I don't want to run 4.x because it doesn't detect an APM device) I sincerely hope the FreeBSD programmers can work all of this kernel instability out quickly. The new 5.0 feature list looks very appealing! But I for one won't run 5.x until it starts living up to the legendary BSD reliability. Good luck folks. You've got your work cut out for you. If anyone wants any additional info about my box, or would like me to do any specific testing, then I'm all for it. Just let me know what you need from me. In the mean time, I'll be installing Linux, I think.
