Screen of Death after sleep

[blaintherapist]

Hey, I'm relatively new to mac. I started almost exactly a year ago with my macbook, and have since upgraded to leopard.

Recently, in the last few weeks i've started getting kernel panics I guess, and the computer gives me the multi language death screen telling me to restart.

This now ALWAYS happens when coming off sleep, and seems to be directly related to anything that has to do with wireless internet activity. ie- if i click on the wireless icon on the top left, or try and surf using safari, try and reconnect with adium, etc.
One thing, is that I am always running azeurus. I've read that maybe a couple of other people have had this problem. Some suggested making sure that my hard disk doesn't turn off when in sleep. I tried that, no dice.
Also, i downloaded onyx and did a pretty big system clean and actually, everything is running faster, but I woke up this morning again, only to crash.
Other people online had azurues info in their crash message, i do not. I have no idea what this kernel panic message means either.

Any ideas? fixes? or whatever?

Thanks!

I found one "partial" solution it seems - it seems reseting the NVRAM (video ram settings) helped:

However I'm still getting kernel panics as well after sleep, but not all the time (progress???). Mine are coming with any kind of activation of the Finder (click on the dock, double click an icon). You might try looking at the Console application as well as it shows the step by step of the actual applications and what processes they are calling forth (see Utilities folder) - try to note the time of the crash, then scroll through and look for the last culprit at that time. I'm seeing things like the following:

2/9/08 12:33:39 AM com.apple.metadata.mds[34] mds(34,0xf0491000) malloc: *** error for object 0x3694e0: double free

Now I'm not a code expert but words like "fault", "exited abnormally", "illegal instruction" seem to be indicative of a problem - I just haven't narrowed it down yet.

Finally, you might try starting up in "Safe Mode" - hold the Shift key after the chime - and see if the problem persists (I just remembered I should try that). This cuts out 3rd party components that might be futzing with the OS. Also zapping the PRAM (hold down P+R+Command+Option, let the computer 'start' and chime three times, then release) this resets general settings that if corrupted can cause buggy actions.

Hope that helps.

Do you have Azureus running?

It seems there is an airport driver conflict and Azureus has known issues with Leopard.

 

[jtimleck]

no, no Azureus app running - I updated to 10.5.2 as well and thought that would fix it - it has for some, but not for me. I believe it's a USB hub issue - the similarity has to do with others that we have Studio of Cinema display ADC displays - something in the hub and the signals from keyboards, mice or other peripherals seems to not play nicely on waking from sleep. The difficulty is that it isn't easily tested since it seems the computer has to be asleep for LONG periods (i.e. hours) to invoke the crash. So it's not so simple to say "unplug your peripherals" and try it - I am, but it could take DAYS to figure out, if I'm lucky.

 

[zolchew]

I have the very same problem. Freeze after longer sleep period. Any progress with yours?

 

[jtimleck]

I've not got around to trouble shooting it but i understand it's almost certainly the hub in the 17" Apple Display - I have hubs off that and am running a KVM Switch (to switch between screens with a (ick) PC I use). I've read if you run a straight shot from the Mac to your USB objects you should be fine (seems an older hardware incompatibility issue). That doesn't help with the KVM since **it** needs to to have the USB routed through it or no point in having it. If i get around to testing the setup more will post. gl!
