apparent lockup/panic on wake from sleep (macbook)

hi folks,

i got on the parallels train right before RC1. i never had any problems with RC1 or the prior version on my first macbook, which had 1GB of ram.

i received a new macbook from apple the other day (the first had a bad dvd burner). the only difference here is that it has 2GB of ram. but this one seems to be hanging maybe 25% of the time when coming out of sleep. i open the lid and the screen stays black; the only thing that fixes it is power cycling the machine. at the time parallels isnt even running.

when it happens, i think that i've put it to sleep while connected to my home wireless network and woken it up at work, where it tries to join my work network. so i guess its possible its related to the new automatic network switching, except that it was happening with RC1 as well.

since i used dd to clone my first macbook onto the old one, i thought it was possible that the OS got messed up, so i did an archive and install... and it seems to be fixed. of course now the parallels hypervisor kernel extensions are not loaded. i should have tried removing the kernel modules before reinstalling the OS to really troubleshoot this correctly, but for now it seems like the problem might be related to parallels.

any ideas? if i switch to non-VTx mode, does the hypervisor not load? thanks.
 
I'm not too sure this has anything to do with Parallels. On my Macbook, I've noticed that if I hit shut down and close the lid (which causes a sleep), it will have exactly the effect you've described. In my case, if you look closely enough, there is sometimes text on the screen but it's difficult to see. I haven't gotten a chance to contact Apple about it though.
 
IMHO i dont think its the "black screen" problem. this happens on my G4 powerbook from time to time, and if i hit power-S, it goes to sleep and when i wake it up again its fine.

in this case, its a hard hang. power-s doesnt do anything, nor does closing the lid.

its been 2 days now without the parallels hypervisor installed and no hangs. after another day i'm going to reinstall RC2 and try again; if it starts hanging, i'm sure the problem is parallels.

and then if the parallels team still doesnt think this is legit, i guess i'll contest the preorder charge i just made on friday, because i dont want something on my machine that's causing it to hang all the time.
 
I'm getting this total hang on my Mac Pro. It looks like its woken up from sleep ok but everything is frozen except the mouse cursor.

Its damn annoying but Parallels is vital to my job.

well as it turns out, my problem was the apple wireless driver, combined with an older base station. for a while i had to set my 'beacon interval' to 50ms on the base station, but now with newer firmware and new airport drivers on the macbook, no more kernel panics.

do you have wireless on your mac pro?
