Well, I proceeded as I told you I would, applied your patch and even if it didn't solve the problem (bge still doesn't resume) at least it improved the previous situation given that now it doesn't loop timing out once and again as before. You can find a tail from /var/log/messages in here: http://pastebin.com/f643555f7 As you can see, the first 3 lines corresponds to "kldload if_bge" Line number 4 is "acpiconf -s3" At line number 17 bge0 finally fails and let's the machine wake up at line 18. Then, as soon as I could I issued a "ifconfig bge0" to see what I could get .. that's what you can see from line 20 to line 41. (as you can see in there, I found there are problems resuming umass devices as well ... ) Line 42 to 53 correspond to "kldnuload if_bge" .. which, by the way, once unloaded, I could load it again but bge0 never showed on "ifconfig". Line 54 till the end correspond to "umount_msdos /dev/ad0s1" ... which ended with pulling the pendrive out as the system coldn't umount it ... I also found I get wpi0 messages on resume .. it spouts: wpi0 could not lock memory wpi0 could not lock memory wpi0 could not lock memory wpi0 could not lock memory wpi0 could not lock memory wpi0 could not lock memory wpi0 could not lock memory and then it let's the system resume. All in all .. there's _a_lot_of_problems_on_resume_ Pyun, if you'd like me to try a new patch or to do some tests or whatever, just let me know. I'm here awaiting orders :) Best Regards Gonzalo Nemmi
