Hi Nate, I know you've already replied to one of my previous emails on this subject, but I thought I'd chime in with my info here just in case this thread actually catches Soren's attention. :) I've been yelling about this regression as loud as I dare without potentially annoying any developers capable of fixing it. I even opened a PR (misc/59876). Here are two of my most recent emails about it: http://article.gmane.org/gmane.os.freebsd.current/35631 http://article.gmane.org/gmane.os.freebsd.current/35660 My laptop is an IBM Thinkpad A30p. Here's my boot -v dmesg.boot: http://www.wingnet.net/~jesse/freebsd-5.2-rc1.dmesg.boot Also, I've noticed, like you, that I can suspend and resume fine as long as apmd isn't running and the kernel doesn't try to "cleanly" reset the ATA channels. I think it's an ATAng thing because my `acpiconf -s 3` worked in 5.1-RELEASE, but now it too is busted in 5.2-BETA and 5.2-RC1. And finally, I even went so far as to update my: /usr/src/sys/dev/ata/ata-lowlevel.c To version 1.25 (5.2-RC1 ships with v1.24) from CVS and recompile my kernel, but I still hang in the exact same way on resume. Help! 5.2-RELEASE will be here soon! -- Jesse Guardiani, Systems Administrator WingNET Internet Services, P.O.
